Section 17 ROM
17.9.1
Follow the procedure shown in the program/program-verify flowchart in figure 17.21 to write data
or programs to flash memory. Performing program operations according to this flowchart will
enable data or programs to be written to flash memory without subjecting the device to voltage
stress or sacrificing program data reliability. Programming should be carried out 32 bytes at a
time.
The wait times (x, y, z, , ß,
and 2 (FLMCR1, FLMCR2) and the maximum number of programming operations (N) are shown
in table 20.10.
