10.2.4
The timer control registers (TCR) are 8-bit registers. The ATU has ten TCR registers. one for each
channel.
Each TCR is an 8-bit readable/writable register that selects whether an internal clock or external
clock is used for channels 1 to 5.
When an internal clock is selected, TCR selects the value of " further scaled from clock ' scaled
with prescaler register 1 (PSCR1). Scaled clock " can be selected, for channels 1 to 10 only, from
on the rising edge.
When an external clock is selected (channels 1 to 5 only), TCR selects whether TCLKA or
TCLKB is used, and also performs edge selection.
Each TCR is initialized to H'00 by a power-on reset, and in hardware standby mode and software
standby mode.
