generating circuit
(divided by 3)
Data is set automatically from each reload
register when timer underflows
(auto-reload function).
Notes 1: When CMCK instruction is executed, ceramic resonance is selected.
When CRCK instruction is executed, RC oscillation is selected.
When any instructions are not executed, on-chip oscillator clock
(internal oscillation) is selected.
2: Timer 1 count start synchronous circuit is set
by the valid edge of D8/INT0 pin selected by bits 1 (I11) and 2 (I12)
of register I1.
3: Timer 3 count start synchronous circuit is set
by the valid edge of D9/INT1 pin selected by bits 1 (I21) and 2 (I22)
of register I2.
4: Count source is stopped by clearing to “0.”
