Mode 5 (Dual 8-Bit PWM)
In Mode 5, the duty cycle and the resolution of the PWM outputs
are individually programmable. The maximum resolution of the
PWM output is 8 bits.

Mode 6 (Dual RZ 16-Bit Σ- DAC)
Mode 6 provides a high speed PWM output similar to that of a
Σ-Δ DAC. Mode 6 operates very similarly to Mode 4; however,
the key difference is that Mode 6 provides return to zero (RZ)
Σ-Δ DAC output. Mode 4 provides non-return-to-zero Σ-Δ
DAC outputs. RZ mode ensures that any difference in the rise
and fall times does not affect the Σ-Δ DAC INL. However, RZ
mode halves the dynamic range of the Σ-Δ DAC outputs from
0 V to AVDD down to 0 V to AVDD/2. For best results, this
mode should be used with a PWM clock divider of 4.
If PWM1H is set to 4010H (slightly above one-quarter of FS),
typically P2.6 is low for three full clocks (3 × 80 ns), high for
one-half a clock (40 ns), and then low again for one-half a clock
(40 ns) before repeating itself. Over every 65536 clocks, the
PWM compromises for the fact that the output should be
slightly above one-quarter of full scale by leaving the output
high for two half clocks in four every so often.
For faster DAC outputs (at lower resolution), write 0s to the
LSBs that are not required with a 1 in the LSB position. If, for
example, only 12-bit performance is required, write 0001 to the
4 LSBs. This means that a 12-bit accurate Σ-Δ DAC output can
occur at 3 kHz. Similarly, writing 00000001 to the 8 LSBs gives
an 8-bit accurate Σ-Δ DAC output at 49 kHz.
The output resolution is set by the PWM1L and PWM1H SFRs
for the P2.5 and P2.6 outputs, respectively. PWM0L and PWM0H
set the duty cycles of the PWM outputs at P2.5 and P2.6,
respectively. Both PWMs have the same clock source and clock
divider.

In Mode 7, the PWM is disabled, allowing P2.5 and P2.6 to be
used as normal.
