(2) Interrupt requests
Two types of interrupt requests are available: the INTTAB1CC0 (crest interrupt) signal and INTTAB1OV (valley
interrupt) signal.
The INTTAB1CC0 and INTTAB1OV signals can be culled by using the TAB1OPT1 register.
For details of culling interrupts, see 11.4.3 Interrupt culling function.
• INTTAB1CC0 (crest interrupt) signal: An interrupt signal indicating a match between the value of the 16-bit
counter that counts up and the value of the TAB1CCR0 register
• INTTAB1OV (valley interrupt) signal: An interrupt signal indicating a match between the value of the 16-bit
counter that counts down and the value 0001H
(3) Rewriting registers during timer operation
The following registers have a buffer register and can be rewritten in the anytime rewrite mode, batch rewrite mode,
or intermittent batch rewrite mode.

Timer Q1 option TAB1 option register 1 (TAB1OPT1)
For details of the transfer function of the compare register, see 11.4.4 Operation to rewrite register with transfer
function.
(4) Counting-up/down operation of 16-bit counter
The operation status of the 16-bit counter can be checked by using the TAB1CUF bit of TAB1 option register 0
(TAB1OPT0).
Status of TAB1CUF Bit Status of 16-Bit Counter Range of 16-Bit Counter Value
TAB1CUF bit = 0 Counting up 0000H − m
TAB1CUF bit = 1 Counting down (m + 1) − 0001H
Remark m = Set value of TAB1CCR0 register
