DESCRIPTION

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, Power supply +5V connections. A 0.1µF, low impedance decoupling capacitor should be placed between VDD and

50, 73 GND. This should be located as close to the RTX package as possible.

GND

44, 57,

69, 81

Power supply ground return connections.
