TAKEY [7:0]
00H
ISP enable bit (ISPE) is read-only by default, software must write three specific values 55h, AAh and 5Ah
sequentially to the TAKEY register to enable the ISPE bit write attribute. That is:
MOV TAKEY, #55h
MOV TAKEY, #AAh
MOV TAKEY, #5Ah

EMEN ISPE
00H
The bit 0 (ISPE) of IFCON is ISP enable bit. User can enable overall SM59R16A5 ISP function by setting ISPE
bit to 1, to disable overall ISP function by set ISPE to 0. The function of ISPE behaves like a security key. User
can disable overall ISP function to prevent software program be erased accidentally. ISP registers ISPFAH,
ISPFAL, ISPFD and ISPFC are read-only by default. Software must be set ISPE bit to 1 to enable these 4
registers write attribute.

ISPFAL [7:0]: Flash address-Low for ISP function
The ISPFAH & ISPFAL provide the 16-bit flash memory address for ISP function. The flash memory address
should not include the ISP service program space address. If the flash memory address indicated by ISPFAH
& ISPFAL registers overlay with the ISP service program space address, the flash program/page erase of ISP
function executed thereafter will have no effect.
