General Description
NON-DISCLOSURE
AGREEMENT
REQUIRED
An external clock should be applied to the OSC1 input with the OSC2 pin
not connected (see Figure 1-4 (b)). This setup can be used if the user
does not want to run the CPU with a crystal.
NOTE:
The PLL design requires a 32.768-kHz external frequency for proper
operation.

1.5.4 RESET
This active-low pin is used to reset the MCU to a known startup state by
pulling RESET low. The RESET pin contains an internal Schmitt trigger
as part of its input to improve noise immunity. See Section 5. Resets.
1.5.5 LPRST
The LPRST pin is an active-low pin and is used to put the MCU into low-
power reset mode. In low-power reset mode the MCU is held in reset
with all processor clocks halted. See Section 5. Resets.
