(1) Timer counter register n (TCRn)
Address: F0180H, F0181H (TCR00) to F018EH, F018FH (TCR07)
(n = 00 to 11)
TCRn is a 16-bit read-only register and is used to count clocks.
The value of this counter is incremented or decremented in synchronization with the rising edge of a count
clock.
Whether the counter is incremented or decremented depends on the operation mode that is selected by the
MDn4 to MDn0 bits of TMRn (see 6.3 (3) Timer mode register n (TMRn)).
The count value can be read by reading TCRn.
The count value is set to FFFFH in the following cases.
• When the reset signal is generated
• When the TAU0EN bit of peripheral enable register 2 (PER2) is cleared
The count value is cleared to 0000H in the following cases.
• When the start trigger is input in the capture mode
• When capturing has been completed in the capture mode
Caution The count value is not captured to TDRn even when TCRn is read.
