From user code, flash is programmed using the ROM
utility functions from either C or assembly language.
The flash can be programmed one word at a time if so
desired. Once a new user code routine has been pro-
grammed and verified in flash, the link or call address
to that routine can be enabled. This procedure allows
continued user code execution while dynamic reconfig-
uration of user billing code and tariff schedules occurs.
The initial application code loaded through JTAG dic-
tates the in-application facility and implements recogni-
tion of the in-application request and communication.
The following function declarations show examples of
some of the ROM utility functions provided for in-appli-
cation flash programming.
/* Write one 16-bit word to code address 'dest'.
int flash_write (uint16_t dest, uint16_t data);
To erase, the following function would be used:
/* Erase the given Flash page
int flash_erasepage(uint16_t addr);
* addr: Flash offset (anywhere within page)
* Dest must be aligned to 16 bits.
* Returns 0 = failure, 1 = OK.
*/
