(Modem Unit)
(1) CRM0 (Basic Operation Mode Setting)
CRM0
Initial Value (Note)
The initial value is the value set when a reset is applied by the RESET pin.
B7, B2: ..... Not used
B6: ............ Transmission timing clock selection
B5:
B4, B3: ..... Receive side input IF frequency selection
B1, B0: ..... Device test control bit
B7
—
0: TXCI input: 384 kHz
Transmission data TXD is input synchronized to the rise of TXCI. APLL is
ON.
1: TXCI input: 3.84 MHz TXCO output: 384 kHz (TXCI divided by 10)
Transmission data TXD is input synchronized to the rise of TXCO. APLL
is OFF.
Modulation OFF/ON control
0: Modulation ON
(0,0), (0,1): 1.2 MHz
(1,0):
(1,1):
Since it is used for LSI testing, it is normally set to "0."
