Power Saving Application – Option 2 (MC13110A/MC13111A Only) MPU Clk Divider Clk In SPI Port Clk Out SPI Port LO2 Out LO2 In MC13110A/ MC13111A Microprocessor CD Out/ HW Interrupt Interrupt External Timer VCC Mode EN CD Out/Hardware Interrupt MPU Clock Out CD Out Low Delay after MPU selects Inactive Mode to when CD turns off. CD Turns Off External Timer Pulls Pin Low MPU Initiates Mode Change Timer Output Disabled MPU Initiates Inactive Mode “MPU Clock Out” remains active for a minimum of one count of reference counter after “CD Out/Hardware Interrupt” pin goes high Active/Rx Inactive Interrupt Standby/Rx/Active MPU “Clk Out” Divider Programming The “Clk Out” signal is derived from the second local oscillator. It can be used to drive a microprocessor (MPU) clock input. This will eliminate the need for a separate crystal to drive the MPU, thus reducing system cost. Figure 121 shows the relationship between the second LO crystal frequency and the clock output for each divide value. Figure 122 shows the “Clk Out” register bit values. With a 10.24 MHz crystal, the divide by 312.5 gives the same clock frequency as a clock crystal and allows the MPU to display the time on a LCD display without additional external components.
