interrupt or first interrupt line on a PPI chip it is

the address offset of the chip. For second

interrupt line on a PPI chip it is the address

offset of the PPI chip plus 4. Corresponds to bit

positions in interrupt enable register if the card

has one, otherwise use the address offset of

the interrupting chip. The following pre-defined

constants may be used:

X1 = 0 PPIXC0 = 0

X2 = 4 PPIXC3 = 4

Y1 = 8 PPIYC0 = 8

Y2 = 12 PPIYC3 = 12

Z1 = 16 PPIZC0 = 16

Z2 = 20 PPIZC3 = 20

PPIX = 0 PPIYC7 = 8

PPIY = 8 EXT0 = 0

PPIZ = 16 ADC0 = 0

ADC2 = 8

DAC2 = 8

DAC4 = 16

SATRIG = 12

ISRDATA short: type of data transfer to be performed on

interrupt. The following pre-defined constants

may be used:

ISR_NODATA = –1

ISR_READ_16COUNT = 0

ISR_READ_16COUNTSTAT = 16

ISR_READ_32COUNT = 1

ISR_READ_32COUNTSTAT = 17

ISR_READ_PPIABC = 5

ISR_READ_PPIC = 6

ISR_PC27 = 7

ISR_READ_DATA8 = 8

ISR_READ_DATA16 = 9

ISR_READ_2PPIABC = 13

ISR_READ_3PPIABC = 14

ISR_WRITE_DATA8 = 32

ISR_WRITE_DATA16 = 33

ISR_WRITE_PPIABC = 34

ISR_WRITE_16COUNT = 39

ISR_WRITE_32COUNT = 40

ISR_WRITE_2PPIABC = 41

ISR_WRITE_3PPIABC = 42

SizeReq unsigned long: number of data values in each

buffer.

fContin short: use single buffer if zero, use double

buffering (continuous mode) if non-zero.

Chip1 short: address offset of the first timer/counter

or PPI chip to be read or written:

X1 = 0 X2 = 4 PPIX = 0

Y1 = 8 Y2 = 12 PPIY = 8

Z1 = 16 Z2 = 20 PPIZ = 16
