Note:
10.3.33 Bus Master Interface
The timer counters (TCNT), general registers (TGR), timer subcounter (TCNTS), timer cycle
buffer register (TCBR), timer dead time data register (TDDR), timer cycle data register (TCDR),
timer A/D converter start request control register (TADCR), timer A/D converter start request
cycle set registers (TADCOR), and timer A/D converter start request cycle set buffer registers
(TADCOBR) are 16-bit registers. A 16-bit data bus to the bus master enables 16-bit read/writes. 8-
bit read/write is not possible. Always access in 16-bit units.
All registers other than the above registers are 8-bit registers. These are connected to the CPU by a
16-bit data bus, so 16-bit read/writes and 8-bit read/writes are both possible.

Description
Waveform Retain Enable
Selects the waveform output when synchronous
counter clearing occurs in complementary PWM mode.
The output waveform is retained only when
synchronous clearing occurs within the Tb interval at
the trough in complementary PWM mode. When
synchronous clearing occurs outside this interval, the
initial value specified in TOCR is output regardless of
the WRE bit setting. The initial value is also output
when synchronous clearing occurs in the Tb interval at
the trough immediately after TCNT_3 and TCNT_4 start
operation.
For the Tb interval at the trough in complementary
PWM mode, see figure 10.40.
0: Outputs the initial value specified in TOCR
1: Retains the waveform output immediately before
