Example :After sector erasure (E000H-EFFFH), the program in the RAM area writes data 3FH to address
E000H.
DI
: Disable interrupts (IMF
←"0")
LD
(WDTCR2),4EH
: Clear the WDT binary counter.
LDW
(WDTCR1),0B101H
: Disable the WDT.
LD
(FLSCR),0011_1000B
: Enable command sequence execution.
LD
IX,0F555H
LD
IY,0FAAAH
LD
HL,0E000H
; #### Flash Memory Sector Erase Process ####
LD
(IX),0AAH
: 1st bus write cycle
LD
(IY),55H
: 2nd bus write cycle
LD
(IX),80H
: 3rd bus write cycle
LD
(IX),0AAH
: 4th bus write cycle
LD

NZ,sLOOP1
: Loop until the same value is read.
; #### Flash Memory Write Process ####
LD
(IX),0AAH
: 1st bus write cycle
LD
(IY),55H
: 2nd bus write cycle
LD
(IX),0A0H
: 3rd bus write cycle
LD
(HL),3FH
: 4th bus write cycle, (1000H)=3FH

NZ,sLOOP2
: Loop until the same value is read.
LD
(FLSCR),1100_1000B
: Disable command sequence execution.
JP
XXXXH
: Jump to the flash memory area.
Example :This write control program reads data from address F000H and stores it to 98H in the RAM area.
LD
A,(0F000H)
: Read data from address F000H.
LD
(98H),A
: Store data to address 98H.
