Bits 7 and 6

⎯Reserved: These bits always read as 1. The write value should always be 1.

Bit 5

⎯Buffer Operation B (BFB): Designates whether to use the TGRB register for normal

operation, or buffer operation in combination with the TGRD register. When using TGRD as a

buffer register, no TGRD register input capture/output compares are generated.

This bit is reserved in channels 1 and 2, which have no TGRD registers. This bit always read as 0.

The write value should always be 0.

Description

TGRB operates normally

(initial value)

TGRB and TGRD buffer operation

Bit 4

⎯Buffer Operation A (BFA): Designates whether to use the TGRA register for normal

operation, or buffer operation in combination with the TGRC register. When using TGRC as a

buffer register, no TGRC register input capture/output compares are generated.

This bit is reserved in channels 1 and 2, which have no TGRC registers. This bit always read as 0.

The write value should always be 0.
