KTMCR—KT Modem Control
B/D/F/Type:
0/3/3/KT MM/IO
Address Offset: 4h
Default Value:
00h
Access:
RO, RW
Size:
8 bits
The Modem Control Register controls the interface with the modem. Since the FW
emulates the modem, the Host communicates to the FW via this register. Register has
impact on hardware when the Loopback mode is on.
Note:
Reset: Host system Reset or D3->D0 transition.
