This section describes the analog module. The analog module is
designed to be use in conjunction with the analog-to-digital converter
module for monitoring temperature, charge and discharge currents in
smart battery applications.
The analog module uses clock signals from the CGM’s PLL, therefore
the PLL must be running — PLLON bit in the PLL control register must
be set. (See
