(6) TAAn I/O control register 4 (TAAnIOC4)

The TAAnIOC4 register is an 8-bit register that controls the timer output.

This register can be read or written in 8-bit or 1-bit units.

Reset sets this register to 00H. This register is not reset by stopping the timer operation (TAAnCTL0.TAAnCE = 0).

Cautions 1. Accessing the TAAnIOC4 register is prohibited in the following statuses. For details, see 3.4.9

(2) Accessing specific on-chip peripheral I/O registers.

• When the CPU operates with the subclock and the main clock oscillation is stopped

• When the CPU operates with the internal oscillation clock

2. The TAAnIOC4 register can be set only in the interval timer mode and free-running timer mode.

Be sure to set the TAAnIOC4 register to 00H in all other modes (for details of the mode setting,

see 7.4 (2) TAAn control register 1 (TAAnCTL1)). The TAAnIOC4 register setting is invalid if the

TAAnCCR0 and TAAnCCR1 registers are set to the capture function, even if the free-running

timer mode is set.
