DATAIN
EQU
$0081
;Input Register for SPI. Also used for a Serial–to–Parallel transformation.
VALUE
EQU
$0082
;Register to store the SPI. Also used for a Serial–to–Parallel transformation.

INITIALIZE THE DATA REGISTERS AND THEIR DATA DIRECTION BIT REGISTERS
LDA
#$FE
;Configuration PortA as the SPI Port.
STA
DDRA
;All but Bit 0 will be outputs.
LDA
#$FF
STA
DDRB
;Configure Register B as an output. SIOP is not used for the MC33298, but is available for
another peripheral.
STA
DDRC
;Configure Register C as an output
STA
DDRD
;Configure Register D as an output
LDA
#%00010000
;Initialize the SIOP Control Register.
STA
SCR
;Disable SIOP by clearing Bit 6.
SELECT THE DESIRED OUTPUTS
TOP
LDA
STA
#$55
VALUE
Select outputs of MC33298 to be turned “on.” This instruction is left inside the loop to include
changes while running the program. A set bit will cause the associated MC33298 output to be
“off.” The value register is uncorrupted by the serial–to–parallel conversion.
BSET
4,PORTA
;Reset the MC33298.
BCLR
4,PORTA
;Also establishes a + or – trigger source
BSET
4,PORTA
;The MC33298 is reset with a logic low.
BCLR
5,PORTA
;Enable MC33298 by pulling CSB (chip select bar) low. Within the MC33298 the Fault Status is
transferred to the MC33298 Serial Register at a falling edge of CSB.
LDA
VALUE
;Select outputs to be turned “on.”
STA
DTOUT
;Save Output Word (Value) to check for fault.
