Buffer operation, provided for channels 0 and 3, enables TGRC and TGRD to be used as buffer
registers.
Buffer operation differs depending on whether TGR has been designated as an input capture
register or a compare match register.
Table 11.28 shows the register combinations used in buffer operation.
