StatusNormal
; Fixes FLAPLC to “FFH”
; Clears & restarts WDT
; Self programming is started
; Checks blank check error
; Performs abnormal termination processing when an error
; occurs.
; Clears FLCMD register
; Clears flash status register
; PFCMD register control
; FLPMC register control (sets value)
; FLPMC register control (inverts set value)
; Sets normal mode via FLPMC register control (sets value)
; Checks completion of write to specific registers
; Repeats the same processing when an error occurs.
; After the specific sequence is correctly executed, restore
; the CPU clock to its setting before the self programming
; Restores interrupt mask flag
