; (4.0 V to 5.5 V
; Sets flash control command (block erase)
; Sets number of block to be erased (block 7 is specified here)
; Fixes FLAPL to “00H”
; Sets erase block compare number (same value as that of FLAPH)
; Fixes FLAPLC to “00H”
; Clears flash status register
; Clears & restarts WDT
; Self programming is started
; Checks execution result
; Normal termination
; Checks whether to re-execute the erase command.
