Reset In
RESET
Primary reset input to the device. Asserting RESET immediately
resets the CPU and peripherals.
I
Reset Out
RSTOUT
Driven low for 128 CPU clocks when the soft reset bit of the system
configuration register (SCR[SOFTRST]) is set. It is driven low for 32K
CPU clocks when the software watchdog timer times out or when a
low input level is applied to RESET.

I/O
External Clock In
EXTAL
Always driven by an external clock input except when used as a
connection to the external crystal when the internal oscillator circuit is
used. The clock source is configured during reset by CLKMOD[1:0].
I
Crystal
XTAL
Used as a connection to the external crystal when the internal
oscillator circuit is used to drive the crystal.
O
Clock Out
CLKOUT
This output signal reflects the internal system clock.
