Notes 1: Timer 1 count start synchronous circuit is set
by the valid edge of P1
3
/INT pin selected by
bits 1 (I1
1
) and 2 (I1
2
) of register I1.
2: Count source is stopped by clearing to
“
0.
”
3: When the WRST instruction is executed at
WDF1 flag =
“
1,
”
WDF1 flag is cleared to
“
0
”
and the next instruction is skipped.
When the WRST instruction is executed at
WDF1 flag =
“
0,
”
skip is not executed.
4: When the DWDT and WRST instructions are
executed continuously, WEF flag is cleared to
“
0
”
and reset by watchdog timer is not executed.
