MODULE REGISTERS - SM8000 SERIES CONTROLLER - A24 / A32 - EXTENDED MEMORY

This module is assigned 1 k (1024) bytes of memory as shown in the SMIP II Configuration/Relay Register Map for A24/A32 address space. The upper 512 bytes of memory space are unused. The lower 512 bytes of memory are split in half, and form the standard module configuration and relay registers. The following describes these registers.

	Control Register – Read and Write
ADDR	Plug-In LA+0x100
		0 = Normal operation
D15	Reset	1 = Optical module reset
	Module 4	Resets the optical module located at module base address plus 8h.
		See Typical Optical Multi Switch Operation.
		0 = Normal operation
D14	Reset	1 = Optical module reset
	Module 3	Resets the optical module located at module base address plus 6h.
		See Typical Optical Multi Switch Operation.
		0 = Normal operation
D13	Reset	1 = Optical module reset
	Module 2	Resets the optical module located at module base address plus 4h.
		See Typical Optical Multi Switch Operation.
		0 = Normal operation
D12	Reset	1 = Optical module reset
	Module 1	Resets the optical module located at module base address plus 2h.
		See Typical Optical Multi Switch Operation.
D11-D10	Unused
		0 = Normal polarity relay data is read back from this module
		1 = Inverted polarity relay data is read back from this module
D9	Relay Data Read	Pon state = 0
	Back Polarity Bit	This bit may be used to invert the relay data read back from the
		plug-in module. Control, Delay, and Status Register read backs are
		not effected by this bit.
D8	ACFAILN Enable	0 = ACFAILN is enabled to reset this module's relays
		1 = ACFAILN is disabled from resetting this module's relays
	Bit
		Pon state = 0
