●
On-chip power-on reset.
On-chip crystal oscillator with an operating range of 1 MHz to 24 MHz.
●
4 MHz internal RC oscillator trimmed to 1 % accuracy that can
optionally be used as the system clock. When used as the CPU clock,
does not allow CAN and USB to run.
●
On-chip PLL allows CPU operation up to the maximum CPU rate
without the need for a high frequency crystal. May be run from the
main oscillator, the internal RC oscillator, or the RTC oscillator.
●
Boundary scan for simplified board testing.
●
Versatile pin function selections allow more possibilities for using
on-chip peripheral functions.
