Section 13 Timer Z
13.3.10 Timer I/O Control Register (TIORA and TIORC)
The TIOR registers control the general registers (GR). Timer Z has four TIOR registers
(TIORA_0, TIORA_1, TIORC_0, and TIORC_1), two for each channel. In PWM mode including
complementary PWM mode and reset synchronous PWM mode, the settings of TIOR are invalid.
TIORA: TIORA selects whether GRA or GRB is used as an output compare register or an input
capture register. When an output compare register is selected, the output setting is selected. When
an input capture register is selected, an input edge of an input capture signal is selected. TIORA
also selects the function of FTIOA or FTIOB pin.
