EI2, EI1
8, 7
EXTERNAL INTERRUPTS 2, 1: Active HIGH level-sensitive inputs to the Interrupt Controller. Sampled on the rising
edge of PCLK. See Timing Diagrams for detail.
EI5-EI3
11-9
EXTERNAL INTERRUPTS 5, 4, 3: Dual purpose inputs; active HIGH level-sensitive Interrupt Controller inputs;
active HIGH edge-sensitive Timer/Counter inputs. As interrupt inputs, they are sampled on the rising edge of PCLK.
See Timing Diagrams for detail.
NMI
4
NON-MASKABLE INTERRUPT: Active HIGH edge-sensitive Interrupt Controller input capable of interrupting any
processor cycle when NMI is set to Mode 0. See the Interrupt Suppression and Interrupt Controller Sections.
INTSUP
5
INTERRUPT SUPPRESS: A HIGH on this pin inhibits all maskable interrupts, internal and external.

POWER CONNECTIONS
VDD
6, 27,
50, 73
Power supply +5V connections. A 0.1
µF, low impedance decoupling capacitor should be placed between VDD and
GND. This should be located as close to the RTX package as possible.
GND
