316 RENESAS

Bit 0: G0NOV

Description

TPC output group 0 operates normally (output value updated according

to compare-match A of the ITU channel selected by TPCR) (initial

value)

TPC output group 0 operates in non-overlap mode (1 output and 0

output can be performed independently according to compare-match A

and B of the ITU channel selected by TPCR)

11.3

Operation

11.3.1

Overview

When corresponding bits in the PBCR1, PBCR2, NDERA and NDERB registers are set to 1, TPC

output is enabled and the PBDR data register values are output. After that, when the compare-

match event selected by TPCR occurs, the next data register contents (NDRA and NDRB) are

transferred to the PBDR and output values are updated. Figure 11.2 illustrates the TPC output

operation.

Figure 11.2 TPC Output Operation

If new data is written in next data registers A and B before the next compare-match occurs, a

maximum 16 bits of data can be output at each successive compare-match. See section 11.3.4,

TPC Output Non-Overlap Operation, for details on non-overlap operation.
