Bits 6 to 4—I/O Control B2 to B0 (IOB2 to IOB0): These bits select the GRB function.

Bit 6

IOB2

Bit 5

IOB1

Bit 4

IOB0

Function

No output at compare match

(Initial value)

0 output at GRB compare match*

1 output at GRB compare match*

GRB is an output

compare register

Output toggles at GRB compare match

(1 output in channel 2)*

GRB captures rising edge of input

GRB captures falling edge of input

GRB captures both edges of input

GRB is an input

compare register

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. When this setting is made, 1

output is selected automatically.

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.

Bit 2

IOA2

Bit 1

IOA1

Bit 0

IOA0

Function

No output at compare match

(Initial value)

0 output at GRA compare match*

1 output at GRA compare match*

GRA is an output

compare register
