; Masks all interrupts
; Clears FLCMD register
; Configure settings so that the CPU clock ≥ 1 MHz
; Clears flash status register
; PFCMD register control
; FLPMC register control (sets value)
; FLPMC register control (inverts set value)
; Sets self programming mode with FLPMC register control (sets
; value)
; 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 & restarts WDT
; Self programming is started
; Checks erase error
; Performs abnormal termination processing when an error
; occurs.
; Sets flash control command (block blank check)
; Sets number of block for blank check (block 7 is specified
; here)
; Fixes FLAPL to “00H”
CHAPTER 18 FLASH MEMORY
; Repeats the same processing when an error occurs
; Checks completion of write to specific registers
