Preliminary specification
Error correction and host interface IC for
CD-ROM (SEQUOIA)
SAA7385
Table 61 STAT field description
Table 62 Interrupt register and time-out register: 0xF0AD - 53CF94 address 0x05; note 1
Note
1. This register is used in conjunction with STAT and SEQSTP to determine the cause of an interrupt.
Table 63 INT field description
Table 64 Sequence step register and synchronous transfer register: 0xF0AE - 53CF94 address 0x06; note 1
Note
1. The register fields are described in Table 65.
FIELD
DESCRIPTION
MSG, C/D, I/O
These indicate the phase on the SCSI bus.
VGC
Valid Group Code; set if the group code matches code defined in ANSI X3.131-1986.
TC
Terminate Count; set when transfer count decrements to zero.
PE
Parity Error; set if parity checking is enabled and a SCSI parity error occurs.
GE
Gross Error; set on various error conditions. These errors do not cause interrupts.
INT
Interrupt. Indicates whether device is trying to interrupt the microcontroller.
ID2 to ID0
Specifies the encode destination for selection or re-selection.

FIELD
DESCRIPTION
SEL
Selected; set during selection phase if selected as a target with ATN negated.
SATN
Selected with ATN; set during selection if selected as a target with ATN asserted.
RESEL
Reselected; set during reselection phase if reselected as an initiator.
FC
Function complete; set after any target mode command has been completed.
BS
Bus service. Indicates that another device is requesting service; in target mode it is asserted
whenever the initiator asserts ATN.
DIS
Disconnect. In target mode this is asserted and as a Terminate Sequence or a Command Complete
Sequence command causes disconnection.
ILCMD
Illegal command; set when a reserved code is placed in CMD or when the command is from a mode
group.
SRST
SCSI reset detect. This may be set if a reset on the SCSI bus is detected.
TIMEOUT7 to
TIMEOUT0
Time-out period for response to selection or re-selection.
