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