Memory mapped Hardware
Allen-Bradley Parts
Start up and Shutdown
This chapter describes the start-up and shutdown phases of operation,
including:
using the KTx memory-mapped hardware
running diagnostics on the KTx card
running the host compatibility test (M16 diagnostics)
loading the protocol file
initialization
shutdown
Before you begin building your driver, you must be familiar with the KTx
card's memory-mapped hardware. The following sections describe
memory-mapped hardware bytes :0800h through :080Fh, which may be
needed by your driver.
Assert (Release) Z80 (byte :0802h)
Write a 01h to this address to assert (release) the Z80 and begin execution
of the loaded binary file. Subsequent writes to this address while the Z80
is asserted will have no effect.
De assert (Reset) Z80 (byte :0803h)
Write a 01h to this address to de-assert (reset) the Z80 and halt execution
of the loaded binary file. Subsequent writes to this address while the Z80
is de-asserted will have no effect.
