11.2.8 TPC Output Mode Register (TPMR)
TPMR is an eight-bit read/write register that selects between the TPCâs ordinary output and non-
overlap output modes in group units. During non-overlap operation, the output waveform cycle is
set in ITU general register B (GRB) for use as the output trigger and a non-overlap period is set in
general register A (GRA). The output value then changes on compare matches A and B. For
details, see section 11.3.4, TPC Output Non-Overlap Operation. TPMR is initialized to H'F0 by a
reset. It is not initialized in standby mode.

⢠Bits 7â4 (Reserved): These bits are always read as 1. The write value should always be 1.
⢠Bit 3 (Group 3 Non-Overlap Mode (G3NOV)): G3NOV selects ordinary or non-overlap mode
for TPC output group 3 (TP15âTP12).
Bit 3: G3NOV

Description
TPC output group 3 operates normally (output value updated
according to compare match A of the ITU channel selected by TPCR)
(Initial value)
TPC output group 3 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)
⢠Bit 2 (Group 2 Non-Overlap Mode (G2NOV)): G2NOV selects ordinary or non-overlap mode
for TPC output group 2 (TP11âTP8).
Bit 2: G2NOV
0

Description
TPC output group 2 operates normally (output value updated
according to compare match A of the ITU channel selected by TPCR)
(Initial value)
TPC output group 2 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)
