PHY_SEL
The PHY_SEL control register is used mainly for selecting the communication mode and
controlling the connection status between the PS2000A and the network server.
The bit definition of PHY_SEL is shown in Table 7.

D4 (CA/AN): In Modem mode, if D4=1, the PS2000A connects to the network server
with Call dial mode; if D4=0, the PS2000A is waiting for a connection to the network
server in the Answer dial mode.
D5, D6 (Reserved): Bits reserved for system expansion.
D7 (Link_CTL): Controls the connection between the PS2000A and the network
server.
The MCU controls the logical or physical connection between the PS2000A and the
network server through Link_CTL. When Link_CTL = 0, the PS2000A is disconnected
from the network server; when Link_CTL = 1, the PS2000A is connected to the network
server.
