Motorola MVME2400 manual 16/32-Bit Timers

Block Diagram

The interval timers use the OSC clock input as their clock source. The MVME240x drives the OSC pin with a 14.31818MHz clock source.

16/32-Bit Timers

There is one 16-bit timer and four 32-bit timers on the MVME240x. The 16-bit timer is provided by the PIB. The Hawk device provides the four 32- bit timers that may be used for system timing or to generate periodic interrupts. For information on programming these timers, refer to the data sheet for the W83C553 PIB controller and to the MVME2400-Series VME Processor Module Programmer’s Reference Guide .
