Description

CLKOUT

Clock Generation

MPC5642A clock output for the calibration bus interface

ENGCLK

Clock Generation

Clock for external ASIC devices

EXTAL

Clock Generation

Input pin for an external crystal oscillator or an external clock

source based on the value driven on the PLLREF pin at reset

PLLREF

Clock Generation

Reset/Configuration

PLLREF is used to select whether the oscillator operates in

xtal mode or external reference mode from reset. PLLREF = 0

selects external reference mode. On the 324 TEPBGA

package, PLLREF is bonded to the ball used for PLLCFG[0]

for compatibility with MPC55xx devices.

For the 176-pin QFP and 208-ball BGA packages:

0: External reference clock is selected

1: XTAL oscillator mode is selected

For the 324-ball BGA package:

If RSTCFG is 0:

0: External reference clock is selected

1: XTAL oscillator mode is selected

If RSTCFG is 1, XTAL oscillator mode is selected.
