14.7 Simultaneous Rewrite
14.7.1
Overview
Simultaneous rewrite describes the ability to change the compare/start value
and the output logic of multiple channels at the same time.
The corresponding data and control registers (TAUJnCDRm and TAUJnTOLm)
can be written at any time. The new value does not affect the counter
operation or the output signal until simultaneous rewrite is triggered.
Simultaneous rewrite can be triggered by the counter on the master channel
reaching a certain value.
The following table shows the settings for simultaneous rewrite
(TAUJnRDM.TAUJnRDMm = 0).
