Section 14 Timer Unit (TMU)
Note:
14.2.3
TCOR set the value to be set in TCNT when TCNT underflows.
TCOR are 32-bit readable/writable registers.
TCOR are initialized to H'FFFFFFFF at a power-on reset or manual reset. They are retained in
standby or sleep mode.
14.2.4
TCNT count down upon input of a clock. The clock input is selected using the TPSC2 to TPSC0
bits in the timer control register (TCR).
When a TCNT count-down results in an underflow (H'00000000 → H'FFFFFFFF), the underflow
flag (UNF) in the timer control register (TCR) of the relevant channel is set. The TCOR value is
simultaneously set in TCNT itself and the count-down continues from that value.
TCNT are initialized to H'FFFFFFFF at a power-on reset or manual reset. They are retained in
standby or sleep mode.
