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, ring 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.”
