9. 16-Bit Timer
Bits 6 to 4⎯I/O Control B2 to B0 (IOB2 to IOB0): These bits select the GRB function.

GRB is an output No output at compare match (Initial value)
1
compare register _{0 output at GRB compare match*}1
1
0
1 output at GRB compare match*¹
1
Output toggles at GRB compare match
(1 output in channel 2)*¹*²

0
GRB is an input GRB captures rising edge of input
1
compare register _{GRB captures falling edge of input}
1
0
GRB captures both edges of input
1
Notes: 1. After a reset, the output conforms to the TOLR setting until the first compare match.
2. Channel 2 output cannot be toggled by compare match. This setting selects 1 output
instead.
Bit 3⎯Reserved: This bit cannot be modified and is always read as 1.
Bits 2 to 0⎯I/O Control A2 to A0 (IOA2 to IOA0): These bits select the GRA function.
