signal provided by the internal oscillator. If a clock fail-

oscillator to serve as the clock source from Power-
on Reset, or wake-up from Sleep mode, until the
primary clock source is available. This allows for
code execution during what would otherwise be the
clock start-up interval and can even allow an appli-
cation to perform routine background activities and
return to Sleep without returning to full power
operation.
both program memory and data EEPROM are rated
to last for many thousands of erase/write cycles –
up to 100,000 for program memory and 1,000,000
for EEPROM. Data retention without refresh is

software control. By using a bootloader routine
located in the protected Boot Block at the top of pro-
gram memory, it becomes possible to create an
application that can update itself in the field.
module provides 1, 2 or 4 modulated outputs for
controlling half-bridge and full-bridge drivers. Other
features include auto-shutdown, for disabling PWM
outputs on interrupt or other select conditions and
auto-restart, to reactivate outputs once the condition
has cleared.
module features automatic wake-up on Start bit and
automatic baud rate detection and supports RS-232,
RS-485 and LIN 1.2 protocols, making it ideally
suited for use in Local Interconnect Network (LIN)
bus applications.

channel to be selected and a conversion to be
initiated without waiting for a sampling period and
thus, reduce code overhead.

time-out range from 4 ms to over 2 minutes that is
stable across operating voltage and temperature.
