Tpc Output Mode Register (Tpmr) - Hitachi H8/3006 Hardware Manual

11.2.10 TPC Output Mode Register (TPMR)

TPMR is an 8-bit readable/writable register that selects normal or non-overlapping TPC output for
each group.
Bit 7
—
Initial value 1
Read/Write —
Group 3 non-overlap
Selects non-overlapping TPC
output for group 3 (TP
Group 2 non-overlap
Selects non-overlapping TPC
output for group 2 (TP
Group 1 non-overlap
Selects non-overlapping TPC
output for group 1 (TP to TP )
Group 0 non-overlap
Selects non-overlapping TPC
output for group 0 (TP to TP )
The output trigger period of a non-overlapping TPC output waveform is set in general register B
(GRB) in the 16-bit timer channel selected for output triggering. The non-overlap margin is set in
general register A (GRA). The output values change at compare match A and B. For details see
section 11.3.4, Non-Overlapping TPC Output.
TPMR is initialized to H'F0 by a reset and in hardware standby mode. It is not initialized in
software standby mode.
Bits 7 to 4—Reserved: These bits cannot be modified and are always read as 1.
