FA'ATA'OTO FA'ATA'OTOLE LAVA (RTSP)

O le RTSP e mafai ai e le tagata fa'aoga ona suia mea e manatua ai polokalame Flash. E fa'ataunu'uina le RTSP i le fa'aaogaina o fa'atonuga o le TBLRD (Table Read) ma le TBLWT (Table Write), le resitala TBLPAG, ma le NVM Control registers. Faatasi ai ma le RTSP, e mafai e le tagata faʻaoga ona tape se itulau e tasi o le Flash memory ma le polokalame pe lua upu faʻatonu pe oʻo atu i le 128 upu faʻatonu i nisi masini.

RTSP Galuega
The dsPIC33/PIC24 Flash program memory array is organized into erase pages that can contain up to 1024 instructions. The double-word programming option is available in all devices in the dsPIC33/PIC24 families. In addition, certain devices have row programming capability, which allows the programming of up to 128 instruction words at a time. Programming and erase operations always occur on an even double programming word, row or page boundaries. Refer to the “Flash Program Memory” chapter of the specific device data sheet for the availability and sizes of a programming row, and the page size for erasing. The Flash program memory implements holding buffers, called write latches, that can contain up to 128 instructions of programming data depending on the device. Prior to the actual programming operation, the write data must be loaded into the write latches. The basic sequence for RTSP is to set up the Table Pointer, TBLPAG register, and then perform a series of TBLWT instructions to load the write latches. Programming is performed by setting the control bits in the NVMCON register. The number of TBLWTL and TBLWTH instructions needed to load the write latches is equal to the number of program words to be written.

Fa'aaliga: E fautuaina le resitala o le TBLPAG a'o le'i suia ma toe fa'afo'i pe a uma ona fa'aoga.

FAATUATUA
I luga o nisi masini, o le Configuration bits o loʻo teuina i le itulau mulimuli o le polokalame Flash user memory space i se vaega e taʻua, "Flash Configuration Bytes". Faatasi ai ma nei masini, o le faʻatinoina o se faʻagaioiga tape itulau i le itulau mulimuli o le manatua o le polokalame e tape ai le Flash Configuration bytes, lea e mafai ai ona puipuia code. O le mea lea, e le tatau i tagata fa'aoga ona fa'atino galuega tape itulau i le itulau mulimuli o le manatua o le polokalame. E le o se popolega lea pe a teu le Configuration bits i le Configuration memory space i se vaega e taʻua, "Resitala Faiga Faʻatonu". Va'ai i le Fa'afanua o le Fa'atonuina o Polokalama i le vaega o le "Memory Organization" o le pepa fa'amatalaga o masini fa'apitoa e iloa ai po'o fea o lo'o i ai fasi Fa'atonu.

Fa'agaioiga Fa'apolokalame Flash
A program or erase operation is necessary for programming or erasing the internal Flash program memory in RTSP mode. The program or erase operation is automatically timed by the device (refer to the specific device data sheet for timing information). Setting the WR bit (NVMCON[15]) starts the operation. The WR bit is automatically cleared when the operation is finished. The CPU stalls until the programming operation is finished. The CPU will not execute any instructions or respond to interrupts during this time. If any interrupts occur during the programming cycle, they will remain pending until the cycle completes. Some dsPIC33/PIC24 devices may provide auxiliary Flash program memory (refer to the “Memory Organization” chapter of the specific device data sheet for details), which allows instruction execution without CPU Stalls while user Flash program memory is being erased and/ or programmed. Conversely, auxiliary Flash program memory can be programmed without CPU Stalls, as long as code is executed from the user Flash program memory. The NVM interrupt can be used to indicate that the programming operation is complete.
