Main Program
reset_scsi_hw()
If a reset is occurring, this routine delays until the reset is complete.
Subsequently, the hardware interrupts are reset, the hardware select
register is enabled and the sense keys are set for a Unit Attention.
background_code_load
The code load function loads new firmware, performs a soft reset, or
updates the active/inactive image information.

Disable watchdog timer
Enable serial port
Compute the checksum on the config data structure. Hang if Invalid.
Valid
Clear sense and host unit attention keys.
Copy config register values to the config register map.
Call
tws_setup
to initialize pointers to the TWS data and control registers.
Call
tws_init
to write chip ID, intermediate clock frequency, and enable
acknowledgement after receiving a data byte.
Map SCSI interrupts to External Interrupt 1.
Map DMA interrupts to External Interrupt 0.
Set interrupt priority levels.
Call
init_time_keeping
to initialize and start Timer 0
Wait for reset to clear.
Reset hardware interrupts.
Set unit attention for power on reset or microcode change.
Disable watchdog timer.
Sequentially execute instructions in config program memory.
These instructions are generated by executing
config.exe
.
background_code_load
CODE_LOAD_ENABLED
cl_status !=busy
cl_status == busy
Depending on the code load flags, this
function loads new firmware from external
data memory through the TWS bus to the
serial EEPROM, performs a soft reset, or
updates the active/inactive image
information.
Call
gather_TWS_input
to initialize, to read values of temperature
sensor, or to gather status information from the LM78
