Timer I/O Control Register (TIOR)

TIOR is an 8-bit register. The ITU has five TIORs, one in each channel.

TIOR1

TIOR2

TIOR3

TIOR controls the general registers. Some functions differ in PWM

mode. TIOR3 and TIOR4 settings are ignored when complementary

PWM mode or reset-synchronized PWM mode is selected in

channels 3 and 4.

Each TIOR is an 8-bit readable/writable register that selects the output compare or input capture

function for GRA and GRB, and specifies the functions of the TIOCA and TIOCB pins. If the

output compare function is selected, TIOR also selects the type of output. If input capture is

selected, TIOR also selects the edge or edges of the input capture signal.

TIOR is initialized to H'88 by a reset and in standby mode.

Bit 7—Reserved: This bit cannot be modified and is always read as 1.
