Power Saving Operating Modes
When the MC13110A/B or MC13111A/B are used in a
handset, it is important to conserve power in order to prolong
battery life. There are five modes of operation for the
MC13110A/MC13111A; Active, Rx, Standby, Interrupt, and
Inactive. The MC13110B/MC13111B has three modes of
operation. They are Active, Rx, and Standby. In the Active
mode, all circuit blocks are powered. In the Rx mode, all
circuitry is powered down except for those circuit sections
needed to receive a transmission from the base. In the
Standby and Interrupt Modes, all circuitry is powered down
except for the circuitry needed to provide the clock output for
the microprocessor. In the Inactive Mode, all circuitry is
powered down except the MPU serial interface. Latch
memory is maintained in all modes. All mode functions are
the same for the MC13110B/MC13111B, except that there is
no Inactive mode. With the B” version the MPU Clock is
always running so that there can never be a register reset if
the memory is disturbed. Figure 118 shows the control
register bit values for selection of each power saving mode
and Figure 118 shows the circuit blocks which are powered in
each of these operating modes.

MC13111B Only)
When the handset is in standby, power can be reduced by
entering a “low power” mode and periodically switching to
“sniff” mode to check for incoming calls. Figure 119. shows
an application where the “Clk Out” pin provides the clock for
the MPU. In this application, the 2nd LO and MPU clock run
continuously. The MPU maintains control at all times and sets
the timing for transitions into the “sniff” mode. Power is saved
in the low power mode by putting the MC13110B/MC13111B
into its “Standby” mode. Only the 2nd LO and MPU clock
divider are active. By programming the MPU clock divider to
a large divide value of 20, 80, or 312.5 this will reduce the
MPU clock frequency and save power in the MPU.
