mitted bit periods and are referenced to the TRANSMIT (!) Frame Counter. Only the 7 LSBits of the 9-bit value are program-
mable. The two MSBits have fixed values which depend on whether base station or handset is selected. For
RFRX_PWR_ON, the two bits are “00” on the base and “01” on the handset. For RFRX_PWR_OFF, the two bits are “01”
on the base and “10” on the handset.
