Notes: *1 After reset, the value output is 0 until the first compare match occurs.
*2 Channel 2 has no compare-match driven toggle output function. If it is set for toggle, 1
is automatically selected as the output.
• Bit 3 (Reserved): Bit 3 always is read as 1. The write value should always be 1.
• Bits 2–0 (I/O Control A2–A0 (IOA2–IOA0)): IOA2–IOA0 select the GRB function.
