TRG — Trigger Assignment Bit
PSH[8:4] — Prescaler Clock High Time Field
The TRG bit allows the software to assign the ETRIG[2:1] pins to
queue 1 and queue 2.
The PSH field selects the QCLK high time in the prescaler.
See
clock frequency (f
range, the PSH field selects the high time of the QCLK, which can
range from 1 to 32 system clock cycles. The minimum high time for
the QCLK is specified as t
which enable a range of QCLK high times.
