The MAD2WD1 operates from a 13 MHz system clock, which is generated from the
13Mhz VCXO frequency. The MAD2WD1 supplies a 6.5MHz or a 13MHz internal clock for
the MCU and system logic blocks and a 13MHz clock for the DSP, where it is multiplied
to 78 MHz DSP clock. The system clock can be stopped for a system sleep mode by dis-
abling the VCXO supply power from the CCONT regulator output. The CCONT provides a
32kHz sleep clock for internal use and to the MAD2WD1, which is used for the sleep
mode timing. The sleep clock is active when there is a battery voltage available; i.e.,
always when the battery is connected.
