Initial value (*)
CR0
* the initial value is set when a reset signal is supplied by a PDN.
B7: PS/CS selection
1/CS (4 Clock recovery DPLLs are on.)
0/PS (2 Clock recovery DPLLs are on.)
B6: Transmit timing clock selection
0/TXCI input: 384 kHz.
TXCO output: 384 kHz output from APLL. Transmit data TXD is input in synchronization
with the rising edge of TXCI (APLL is on.)
1/TXCI input: 3.84 MHz.
TXCO output: 384 kHz (one-tenth of the TXCI frequency). Transmit data TXD is input in
synchronization with the rising edge of TXCO (APLL is off.)
B5: Modulation on/off control
1/modulation OFF (with phase fixed)
0/modulation ON.
B4, B3: Receiver input IF frequency selection
(0, 0), (0, 1):
1.2 MHz
(1, 0):
10.8 MHz
(1, 1):
10.7 MHz/10.75 MHz
