MICROCONTROLLER INTERFACE
.
The modem block interfaces to the microcontroller via the interrupt signal MSK_INT and via the control and data SFRs
MCON, MSTAT and MBUF. The MSK modem receive and transmit registers are both accessed via the SFR MBUF.
Writing to MBUF loads the transmit register and reading MBUF accesses a physically separate receive register.
10.12.1.1 MSK Modem Control Register (MCON)

MSK Modem Control Register (SFR address C8H)

Description of MCON bits
Note
1.
If both the transmitter and the receiver are disabled (MTEN = 0 and MREN = 0), the clock of the MSK modem is
switched off. It is advised to use this state for power saving.

Preamble pattern.
These 4 bits define the modems preamble pattern.
RX/TX frequency.
These 2 bits define the modem transmit/receive frequency; see
Table 41.
Modem Transmitter Enable.
If set the transmitter is active and MOUT[2:0] will get the
value <100> if no data is transmitted. If reset, MOUT[2:0] will get the value <111> to
zero the currents in the resistive DAC; see note 1.
Modem Receiver Enable.
If set the modem receiver is active and scans for Manchester
data; see note 1.
