Interrupt Service Routines - General
General Functions
Description
req_ack
On data transfers, this routine grabs each
byte and stores the result in the global
variable
rcv_byte
. This variable contains
a copy of what was transferred over the
SCSI bus, whether the phase is data in or
data out.
Returns TRUE if a Reset or the SCSI bus
is not busy.
command_and_data_phases
Retrieves the CDB contents and processes
the SCSI request. Based on the command
line compile options, the CDB is written by
the DMA engine or through direct I/O.
CDBs with invalid OpCodes result in a
check condition. Otherwise, processing is
continued and the appropriate SCSI
subroutines are invoked.
Returns TRUE if a transfer is incomplete or
if the data transfer of a byte of data failed.
Returns FALSE with or without a check
condition otherwise.
send_data_bytes
Transmits data from the supplied buffer to
the Initiator. Data transfers occur through
DMA (if enabled) or through direct I/O.
get_data_bytes
Receives data from the Initiator and stores
them in the buffer supplied on the function
call.
do_code_load
Specialized function for processing the
Vendor Specific Mode 4 Write Buffer
commands to upload firmware to the serial
EEPROM. Based on the status of the TWS
global flag,
cl_status
, and CDB[3], this
function will populate the
code_buffer
or
generate a check condition. The condition
will occur if the TWS bus is busy of if there
was an error on a previous Mode 4 Write
Buffer command.
