5. Various Registers
The main registers are as follows:
Command register
This register specifies each command with an 8-bit code.
If the user program is used, the starting address of the program assigned to the user program memory is
specified.
Nexus status register
This register indicates the chip’s operating condition, linked partner’s ID, and data register status.
SCSI control signal status register
This register indicates the status of the SCSI control signals.
Interrupt status register
This register indicates the interrupt status with an 8-bit code.
Command step register
This register indicates the execution status of each command with an 8-bit step code.
Referencing the interrupt status register and this register permits analysis of error causes.
Group 6/7 command-length setting register
This register sets the group 6/7 command length not defined in the SCSI standard.
Setting this register permits group 6/7-command length decisions.
6. Receive MSG, CMD, Status Buffer (RECEIVE MCS Buffer)
This is a 32-byte receive-only information buffer that holds the message, command, and status information received
from the SCSI bus.
7. Send MSG, CMD, Status Buffer (SEND MCS Buffer)
This is a 32-byte send-only information buffer that holds the message, command, and status information sent on
the SCSI bus.
8. User Program Memory
This is a 512-byte program memory that stores programmable commands. It consists of two 256-byte banks.
9. Data Register
This is a 64-byte FIFO-type data register that holds data when the data phase is executed on the SCSI bus.
