Motorola MVME162 manual Debugger General Information, Bit J22 Pins Description

Debugger General Information

	Bit	J22 Pins	Description
3	Bit #0 (GPI0)	15-16	When this bit is a one (high), it instructs the debugger
			to use local Static RAM for its work page (i.e.,
			variables, stack, vector tables, etc.).
	Bit #1 (GPI1)	13-14	When this bit is a one (high), it instructs the debugger
			to use the default setup/operation parameters in Flash
			or PROM versus the user setup/operation parameters
			in NVRAM. This is the same as depressing the RESET
			and ABORT switches at the same time. This feature
			can be used in the event the user setup is corrupted or
			does not meet a sanity check. Refer to the ENV
			command (Appendix A) for the Flash/PROM defaults.
	Bit #2 (GPI2)	11-12	Reserved for future use.
	Bit #3 (GPI3)	9-10	When this bit is a zero (low), it informs the debugger
			that it is executing out of the Flash memories. When
			this bit is a one (high), it informs the debugger that it is
			executing out of the PROM.
	Bit #4 (GPI4)	7-8	Open to your application.
	Bit #5 (GPI5)	5-6	Open to your application.
	Bit #6 (GPI6)	3-4	Open to your application.
	Bit #7 (GPI7)	1-2	Open to your application.

Note that when the MVME162 comes up in a cold reset, 162Bug runs in Board Mode. Using the Environment (ENV) or MENU commands can make 162Bug run in System Mode. Refer to Appendix A.

2.Configure header J1 by installing/removing a jumper between pins 1 and 2. A jumper installed/removed enables/disables the system controller function of the MVME162.

3.You may configure Port B of the Z85230 serial communications controller via a serial interface module (SIM) which is installed at connector J10 on the MVME162 board. Four serial interface modules are available:

– EIA-232-D DTE (SIM05)

– EIA-232-D DCE (SIM06)

– EIA-530 DTE (SIM07)

– EIA-530 DCE (SIM08)

For information on removing and/or installing a SIM, refer Chapter 2.
