This pin is the input to the low-power
32 kHz crystal oscillator for the Real-
time clock. If the Real-time clock is
disabled or not used, this input must
be left floating or tied to VSS to
minimize any input current leakage.
This pin is the output from the low-
power 32 kHz crystal oscillator for the
Real-Time Clock. This pin is an input
when the RTC is configured to
operate from 50/60 Hz input clock
signals and the 32 kHz crystal
oscillator is disabled.
Power supply for the Real-Time Clock
and associated 32 kHz oscillator.
Isolated from the power supply to the
remainder of the chip. A battery is
connected to this pin to supply
constant power to the Real-Time
Clock and 32 kHz oscillator. If the
Real-time clock is disabled or not
used this output must be tied to Vdd.
Ground.
A Low on this pin indicates that the
CPU has entered either HALT or
SLEEP mode because of execution of
either a HALT or SLP instruction.
JTAG Mode Select Input.
JTAG and ZDI clock input.
Active High trigger event indicator.
JTAG data input pin. Functions as ZDI
data I/O pin when JTAG is disabled.
This pin has an internal pull-up
resistor in the pad.
