Test Register 1
The MVME3100 provides a 32-bit general-purpose read/write register that can be used by software for
PLD test or general status bit storage.
TEST1
General-purpose 32-bit read/write field.
Test Register 2
The MVME3100 provides a second 32-bit test register that reads back the complement of the data in
test register 1.
TEST2
A read from this address returns the complement of the data pattern in test register 1. A write to this
address writes the uncomplemented data to register TEST1.
External Timer Registers
The MVME3100 provides a set of tick timer registers for access to the four external timers implemented
in the timers/registers PLD. These registers are 32-bit registers and are not byte writable. The following
sections describe the external timer prescaler and control registers.
