MX10EXA
In-Application Programming Method
Several Application Program Interface (API) calls are available for use by an application program to permit selective
erasing and programming of FLASH sectors. All calls are made through a common interface, PGM_MTP. The pro-
gramming functions are selected by setting up the microcontroller's registers before making a call to PGM_MTP at
FFFOH. Results are returned in the registers. The API calls are shown in Table 2.

R4L = 00 if pass, non-zero if fail
Input Parameters:
ROH =04h
Return Parameter
R4L
=00 if pass, non-zero if fail
Input Parameters:
R0H
= 05h
R6H
= 00h
R6L
= 00h - security bit # 1 (inhibit writing to FLASH)
0lh - security bit # 2 (inhibit FLASH verify)
02h - security bit # 3 (disable external memory)
Return Parameter:none
Input Parameters:
R0H
= 60h
R6H
= 00h
R6L
= 00H- program status byte
R4L
= status byte
Return Parameter
