1.2.3
1.2.3.1
EXTAL and XTAL are the crystal driver and external clock pins. On reset all the device clocks are derived
from the EXTAL input frequency. XTAL is the crystal output.
1.2.3.2
The RESET pin is an active low bidirectional control signal. It acts as an input to initialize the MCU to a
known start-up state. As an output it is driven ;ow to indicate when any internal MCU reset source triggers.
The RESET pin has an internal pullup device.

For devices assembled in 80-pin and 112-pin packages all non-bonded out
pins should be configured as outputs after reset in order to avoid current
drawn from floating inputs. Refer to
