Chapter 2 External Signal Description
2.2.1
V
I/O buffer circuitry, ACMP and ADC modules, and to an internal voltage regulator. The internal voltage
regulator provides a regulated lower-voltage source to the CPU and other internal circuitry of the MCU.
Typically, application systems have two separate capacitors across the power pins: a bulk electrolytic
capacitor, such as a 10-μF tantalum capacitor, to provide bulk charge storage for the overall system, and a
bypass capacitor, such as a 0.1-μF ceramic capacitor, located as near to the MCU power pins as practical
to suppress high-frequency noise.

1. Not required if using the internal clock option.
2. XTAL is the same pin as PTB6; EXTAL the same pin as PTB7.
3. The RESET pin can only be used to reset into user mode; you can not enter BDM using the RESET pin.
4. IRQ feature has optional internal pullup device.
5. RC filter on RESET/IRQ pin recommended for noisy environments.

BDM can be entered by holding MS low during POR or writing a 1 to BDFR in SBDFR with MS low after
issuing the BDM command.
