Reload Counter 10C (TCNT10C): Reload counter 10C (TCNT10C) is a 16-bit readable/writable

Bit:

Initial value:

R/W: R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W

When TCNT10C = H'0001 in the down-count operation, the value in the reload register

(RLD10C) is transferred to TCNT10C, and a multiplied clock (AGCK1) is generated.

TCNT10C is connected to the CPU via an internal 16-bit bus, and can only be accessed by a word

read or write.

TCNT10C is initialized to H'0001 by a power-on reset, and in hardware standby mode and

software standby mode.

Correction Counter 10D (TCNT10D): Correction counter 10D (TCNT10D) is an 8-bit

readable/writable register that counts on external clock input (TI10) after transfer of the counter

value to correction counter E (TCNT10E). Set TI10 input with bits CKEG1 and CKEG0 in

TCR10. Counting will not be performed on TI10 input unless the count operation is enabled by

bit STR10 in TSTR1.

Bit:

Initial value:

R/W:

R/W

At the external clock input (TI10) (AGCK) timing, the value in this counter is shifted according to

the multiplication factor set by bits PIM1 and PIM0 in timer I/O control register 10 (TIOR10) and

transferred to correction counter E (TCNT10E).

TCNT10D can only be accessed by a byte read or write.

TCNT10D is initialized to H'00 by a power-on reset, and in hardware standby mode and software

standby mode.
