XE1203
4.1.13 Clock Output for external processor
A reference clock could be generated by XE1203 to the external microcontroller. RTParam_Clkout register controls
the CLKOUT pin. When it is set to high then CLKOUT is activated. The generated clock can be 1/4, 1/8, 1/16 or
1/32 of the XE1203 reference oscillator. The different divider ratios can be selected by programming
“ADParam_Clkfreq” register (see the Configuration register section below). The reference oscillator frequency of
39MHz can result 1.22, 2.44, 4.87 or 9.75MHz clock at the CLKOUT pin. This clock is stopped in Sleep Mode.
