Power Saving Operating Modes
When the MC13109A is used in a handset, it is important
to conserve power in order to prolong battery life. There are
five modes of operation; Active, Rx, Standby, Interrupt and
Inactive. In Active Mode, all circuit blocks are powered. In 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 Inactive Mode, all circuitry is
powered down except the MPU interface. Latch memory is
maintained in all modes. Figure 16 shows the control register
bit values for selection of each power saving mode and
Figure 17 show the circuit blocks which are powered in each
of these operating mode.
