Figure 18-23. Example of Internal Verify 1 Operation in Self Programming Mode
Internal verify 1
<1> Set internal verify 1
command (FLCMD = 01H)
<2> Set no. of block for
internal verify, to FLAPH
<3> Set 00H to FLAPL
<4> Set the same value as
that of FLAPH to FLAPHC
<5>
Set FFH to FLAPLC
<6> Clear PFS
<7> Clear & restart WDT counter
Note
(WDTE = ACH)
<8> Execute HALT instruction
<9> Check execution result
Abnormal
(VCERR and WEPRERR flags)
Normal
<11> Normal termination
<10> Abnormal termination
Note This setting is not required when the watchdog timer is not used.
Remark
<1> to <11> in Figure 18-23 correspond to <1> to <11> of internal verify 1 in 18.8.9 (previous page).
