; Sets flash control command (internal verify 1)
; Sets block number for which internal verify is performed,
; to FLAPH (Example: Block 7 is specified here)
; Sets 00H
; Sets FFH
; Clears flash status register
; Clears & restarts WDT
; Self programming is started
; Execution result is stored in variable
; (CmdStatus = 0: normal termination, other than 0: abnormal
; termination)
; Sets flash control command (internal verify 2)
; Sets block number for which internal verify is
; performed, to FLAPH (Example: Block 7 is specified here)
; Sets FLAPL to the start address for verify (Example: Address
; 00H is specified here)
; Sets FLAPLC to the end address for verify (Example: Address
; 20H is specified here)
; Clears flash status register
; Clears & restarts WDT
; Self programming is started
; Execution result is stored in variable
; (CmdStatus = 0: normal termination, other than 0: abnormal
; termination)
