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.
