Figure 37-4. Non Overlapped Center Aligned Waveforms
Note:
When center aligned, the internal channel counter increases up to CPRD and.decreases down
to 0. This ends the period.
When left aligned, the internal channel counter increases up to CPRD and is reset. This ends
the period.
Thus, for the same CPRD value, the period for a center aligned channel is twice the period for a
left aligned channel.
Waveforms are fixed at 0 when:
Waveforms are fixed at 1 (once the channel is enabled) when:
The waveform polarity must be set before enabling the channel. This immediately affects the
channel output level. Changes on channel polarity are not taken into account while the channel
is enabled.
• CDTY = CPRD and CPOL = 0
• CDTY = 0 and CPOL = 1
• CDTY = 0 and CPOL = 0
• CDTY = CPRD and CPOL = 1
