(c) High-speed PWM operation (7-bit PWM)
In the PWM operation mode, there are the normal mode with 8-bit 256 resolution and the high-speed mode
with 7-bit 128 resolution.
Writing 1 at the P7M1 and P7M2 bits of the CNTR1 register gives this mode.
Table 2.6 PWM Cycle and Resolution
(Clock = 10 MHz with the Highest Speed Gear (Instruction Cycle = 400 ns))
(d) CH1-2 PWM mode
This mode causes the 2-channel PWM timer to be a timer and generates width L with the CH1 timer and
the cycle with the CH2 timer to output a PWM wave.
Writing 1 at the CH1-2 bit of the CNTR3 register gives this mode. The timer mode is set irrespective of the
values of the PTX1 and PTX2 bits of the CNTR1 register. A PWM wave is output from the P43 pin con
trolled by OE3 to the compare registers 1 and 2.
To start the operation, write 1 simultaneously at the TPE1 and PTE2 bits of the CNTR2 register. Writing 1
separately at the TPE1 and TPE2 bits changes the duty or cycle. However, when the count value of CH2
agrees with the value of the compare register, both the CH1 and CH2 are simultaneously counter-cleared.
Therefore, the duty or cycle is based on the value of the compare register from the second cycle.
When not in the CH1-2PWM mode, the P43 pin provides the CH1 toggle output or outputs a PWM wave.
The default value of the PWM output is Low level.
Fig. 2.18 PWM Wave Output at CH1-2 PWM Mode
If the cycle of the CH1 timer becomes larger than that of the CH2 timer, a PWM wave is not output. The
CH1 timer should be disabled for an interrupt. The CH2 timer can be used in the same manner as the nor-
mal timer.
