1. DEMOD_PWR_ON, DEMOD_PWR_OFF. Controls internal receive hardware and the RXSW output pin. The turn-on and off times
2. Changes to these values take effect immediately.
3. To enable receive power continuously, clear TX_ENABLE and set SYNC_SEARCH_MODE to FULL_SEARCH (this is the case
4. The polarity of the RXSW output pin is controlled by the RFRX_POLARITY bit in the RFRX_PWR_CTRL register
are given in number of received bit periods and are referenced to the Receive Frame Counter. Only the 7 LSBits of the 9-bit value
are programmable. The two MSBits have fixed values which depend on whether base station or handset is selected. For
DEMOD_PWR_ON, the two bits are “01” on the base and “00” on the handset. For DEMOD_PWR_OFF, the two bits are “10” on
the base and “01” on the handset
in acquisition mode).
