11.2.1
TCNT is an 8-bit readable/writable up-counter. When the timer enable bit (TME) in the timer
control/status register (TCSR) is set to 1, the timer counter starts counting pulses of an internal
clock source selected by clock select bits 2 to 0 (CKS2 to CKS0) in TCSR. When the count
overflows (changes from H'FF to H'00), an overflow flag (OVF) in TCSR is set to 1.
TCNT is initialized to H'00 by a reset and when the TME bit is cleared to 0.
Note: TCNT is write-protected by a password. See Section 11.2.3, Register Access, for details.
11.2.2
Note: * Software can write a 0 in bit 7 to clear the flag, but cannot write a 1 in this bit.
TCSR is an 8-bit readable/writable register that selects the timer mode and clock source and
performs other functions.
Bits 7 to 5 and bit 3 are initialized to 0 by a reset and in the standby modes. Bits 2 to 0 are
initialized to 0 by a reset, but retain their values in the standby modes.
Note: TCSR is write-protected by a password. See section 11.2.3, Register Access, for details.
