I/O control B2 to B0
These bits select GRB functions
Reserved bit
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: Read-only bit, always read as 1.
Bits 6 to 4—I/O Control B2 to B0 (IOB2 to IOB0): These bits select the GRB function.

Notes: 1. After a reset, the output is 0 until the first compare match.
2. Channel 2 output cannot be toggled by compare match. This setting selects 1 output
instead.
