MSK modem
The MSK modem is used for in-band signalling between
handset and base in analog cordless telephone systems
CT0, CT1 and CT1+. The MSK modems receiver and
transmitter can be enabled separately. Receive and
transmit interrupts can wake-up the microcontroller during
itspowersavingIdlemode.Baudratesareprogrammable.
Figure 25 shows the functional diagram of the MSK
modem.
The modem has the following features:
Full-duplex operation via an 8-bit parallel interface
The message is fully Manchester coded/decoded
Automatic detection of 16-bit Manchester preamble
pattern
The last received 4 bits of the preamble pattern are
software programmable
Receiver full, transmitter empty indication bits
Manchester coding and decoding for clock recovery and
early error detection
Programmable input polarity (see WDCON SFR;
Section 6.7.1)
