• Manufacturer Part Number: HD6413003RVF
• Description: microcontroller (MCU)
• Manufacturer: RENESAS [Renesas Technology Corp]

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.
