Description
Timer Enable
When this bit is set to 1, TCNT starts counting.
When this bit is cleared, TCNT stops counting and is
initialized to H'00.
Reserved
The initial value should not be changed.
Reset or NMI
Selects to request an internal reset or an NMI interrupt
when TCNT has overflowed.
0: An NMI interrupt is requested
1: An internal reset is requested
Clock Select 2 to 0
Selects the clock source to be input to. The overflow
frequency for φ = 33 MHz is enclosed in parentheses.
