Fig.20 AMPS/TACS Modem and SAT Controller
Associated Registers
The Modem has 3 dedicated registers for control and data
transfer. There are also bits in the general registers PORT3 and
PORT4 which are used to set up the Modem. The bits are
described in more detail in the relevant section.
MDMSLP
PORT3[3] (Table 59)
This bit determines whether the modem is active or in sleep
mode. The modem is put into sleep mode by turning off the clock
to the Modem and associate circuitry.

Sleep
Modem mode
ENMOD
PORT3[7]
This bit is used to set up the Modem. It must be set to 1 by the
software after a reset and before the Modem is used. It should
then remain at 1.
SATMUX
PORT4[2] (Table 60)
This bit is used to control the source of the Transmitted SAT
signal.

Table 60
NOMPLL
PORT4[4] (Table 61)
In the Data Decoder the modem uses a locally generated
clock to recover the data. NOMPLL selects whether this clock is
forced to lock to the extract Data clock or not. Refer to Data
Decoder section for more detail.
NOMPLL

Normal mode: Data clock locked to incoming clock
Free-running: Data clock unlocked
