Description
Power amplifier level. If PA ramp is enabled, the PA ramps to this target
level. The PA level can be set in the 0 to 63 range. The PA level (with less
resolution) can also be set via the BBRAM; therefore, the MCR setting
should be used only if more resolution is required.

Description
WUC timer reload value, Bits[15:8] of [15:0]. A wake-up event is triggered
when the WUC unit is enabled and the timer has counted down to 0. The
timer is clocked with the prescaler output rate. An update to this register
becomes effective only after WUC_VALUE_LOW is written. See Table 100.
