• Description: 8-bit Single-chip Microcontrollers
• Manufacturer: Renesas Electronics Corporation.

(3) TMPn I/O control register 0 (TPnIOC0)
The TPnIOC0 register is an 8-bit register that controls the timer output (TIOPn0, TIOPn1 pins).
This register can be read or written in 8-bit or 1-bit units.
Reset sets this register to 00H.

shown below (m = 0, 1).
TIOPn1 pin output starts at high level
TIOPn1 pin output starts at low level
Timer output disabled
• When TPnOL1 bit = 0: Low level is output from the TIOPn1 pin
• When TPnOL1 bit = 1: High level is output from the TIOPn1 pin
Timer output enabled (a square wave is output from the TIOPn1 pin).
TIOPn0 pin output starts at high level
TIOPn0 pin output starts at low level
Timer output disabled
• When TPnOL0 bit = 0: Low level is output from the TIOPn0 pin
• When TPnOL0 bit = 1: High level is output from the TIOPn0 pin
Timer output enabled (a square wave is output from the TIOPn0 pin).
