System Clock.

The system clock for the telephone is 13 MHz TCXO, generated by X600. It is processed in IC300 to
provide serial clock for LCD, EEPROM, and IC100. The clock is buffered in IC300 One-C, and then
fed to IC100 IPD as " CPU CLK " . It is available on pin 56 of IC100.
During Stand-By mode, the system clock is not managed from X600 TCXO but from X300 ( " slow
clock " at 32.768 kHz).
