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.
