EXT_INT4
R18
gg
g
IACK
R11
O
Interrupt acknowledge for all active interrupts serviced by the CPU
INUM3
T19
INUM2
T20

POWER DOWN STATUS
PD
D19
O
Power-down mode 2 or 3 (active if high)
I = Input, O = Output, Z = High Impedance, S = Supply Voltage, GND = Ground
PLLV and PLLG signals are not part of external voltage supply or ground. See the CLOCK/PLL documentation for information on how to connect
those pins.
