7 Signal reference

StateMode

I n d i c a t e s that sampling mode is 'State' when high (1). When low (0), sampling

mode is 'Timing'. This bit is useful if a mix of 'State' and 'Timing' sampling is
used within a trace (according to Sequencer program.)

VME64*

T h i s signal is used to identify cycles with VME64 AM-codes, i.e. AM = 00, 01,

03, 06, 07 ,08 ,OC, 38, and 3C.

to select Interrupt Acknowledge cycle type (WR* = 1, SPACE1/0 = 00.) as a
mnemonic in this field (LACK).

SIZ1, SIZO. Select transfer size as requested from master, i.e. LONG, 3BYT,
WORD or BYTE.

ASACK1, ASACKO.

Selects port size as responded by slave (D08, D16, D32).

WR*, ARB*.

This group selects cycle type. The signals WR* and ARB* are

grouped into the group called "Cycle", together with the internally generated bit
"BLOCK", which is set when a VSB block cycle.is detected (in second cycle).

ERR*, ACK*.

Selects between bus error or OK cycle status.
