Timer Control Registers (16TCR)

16TCR is an 8-bit register. The 16-bit timer has three 16TCRs, one in each channel.

Function

16TCR0

16TCR1

16TCR2

16TCR controls the timer counter. The 16TCRs in all

channels are functionally identical. When phase counting

mode is selected in channel 2, the settings of bits CKEG1

and CKEG0 and TPSC2 to TPSC0 in 16TCR2 are ignored.

Clock edge 1/0

These bits select external clock edges

Counter clear 1/0

These bits select the counter clear source

Each 16TCR is an 8-bit readable/writable register that selects the timer counter clock source,

selects the edge or edges of external clock sources, and selects how the counter is cleared.

16TCR is initialized to H'80 by a reset and in standby mode.

Bit 7—Reserved: This bit cannot be modified and is always read as 1.
