ASK/FSK Transceiver with Fractional-N PLL
______________________________________________________________________________________ 23
BIT ID BIT NAME BIT LOCATION (0 = LSB) FUNCTION
MODE FSK or ASK modulation 7
1 = Enable FSK for both receive and
transmit
0 = Enable ASK for both receive and
transmit
T/R Transmit or receive 6
1 = Enable transmit mode of the
transceiver, regardless the state of pin
T/R
0 = Enable receive mode of the transceiver
when pin T/R = 0
MGAIN Manual gain mode 5
1 = Enable manual-gain mode
0 = Disable manual-gain mode
DRX
Discontinuous receive
mode
4
1 = Enable DRX
0 = Disable DRX
OFPS1 Off-timer prescaler 3
OFPS0 Off-timer prescaler 2
Sets the time base for the off timer (see the
Off Timer section)
ONPS1 On-timer prescaler 1
ONPS0 On-timer prescaler 0
Sets the time base for the on timer (see the
On Timer section)

BIT ID BIT NAME BIT LOCATION (0 = LSB) FUNCTION
X None 7 Not used
ACAL Automatic FSK calibration 6
1 = Enable automatic FSK calibration
approximately once every 60s
0 = Disable automatic FSK calibration
CLKOF
Continuous clock output
(even during t
OFF or when
EN pin is low)
5
1 = Enable continuous clock output when CKOUT
= 1
0 = Continuous clock output; if CKOUT = 1, clock
output is active during T
ON (DRX mode) or when
EN pin is high (continuous receive mode)
