Figure 9-27. MCB mode A1 register update in up counter mode
shows the A1 register update in up/down counter mode. Note that A2 can be written at any
time within cycle
n
in order to be used in cycle
n
+ 1. Thus, A1 receives this new value at the next cycle
boundary. Note that the update disable bits OU[
n
] of the EMIOSOUDIS register can be used to disable
update of the A1 register.

9.5.1.1.5
Output Pulse Width and Frequency Modulation Buffered (OPWFMB) mode
This mode (MODE[0:6]=10110b0) provides waveforms with variable duty cycle and frequency. The
internal channel counter is automatically selected as the time base when this mode is selected. The A1
register indicates the duty cycle and the B1 register the frequency. Both the A1 and B1 registers are
double-buffered to allow smooth signal generation when changing the register values on the fly. 0% and
100% duty cycles are supported.
At OPWFMB mode entry, the output flip-flop is set to the value of the EDPOL bit in the EMIOSC[
n
]
register.
