NXP Semiconductors MPC5606S - Features

System Integration Unit Lite (SIUL)
MPC5606S Microcontroller Reference Manual, Rev. 7
Freescale Semiconductor 1187
37.3 Features
The SIUL supports these distinctive features:
•GPIO
— GPIO function on up to 133 I/O pins
— Dedicated input and output registers for each GPIO pin
• External interrupts
— 2 system interrupt vectors for up to 14 interrupt sources
— 14 programmable digital glitch filters
— Independent interrupt mask
— Edge detection
• System configuration
— Pad configuration control
37.4 External signal description
The pad configuration allows flexible, centralized control of the pin electrical characteristics of the MCU
with the GPIO control providing centralized general purpose I/O for an MCU that multiplexes GPIO with
other signals at the I/O pads. These other signals, or alternate functions, will normally be the peripherals
functions. The internal multiplexing allows user selection of the input to chip-level signal multiplexors.
Each GPIO port communicates via 16 I/O channels. In order to use the pad as a GPIO, the corresponding
Pad Configuration Registers (PCR) for all pads used in the port must be configured as GPIO rather than
as the alternate pad function.
Table 37-1 lists the external pins used by the SIUL.
