5.5.41. IO (Set/Read 8 X 3 I/O)

This command is used to set or clear bits on the 8 X 3 I/O connector. It is also used to
read an input byte (8 bits). The status of the I/O banks can be ascertained with the
Secondary I/O screen under the Diagnostics menu. Refer to Chapter 3: User Interface.

INT board, nLevel, nInputBit, nOnOff, Label
board Board = 1.
nLevel Level of interrupt where:
0 = turn off
1 = jump to label (abort all motion)
2 = jump to label (don't abort motion)
3 = jump to label, turn off interrupt, (no abort)
4 = jump to label, turn off interrupt, (abort motion)
nInputBit Input bit number (0 to 15) 16 IN/8 OUT I/O bus input bit.
Valid iSBX-IO48 Input Bit ($000 to $127).
Input bit number (16 to 39) 8 X 3 I/O bus input bit.
nOnOff 0 = int when nInputBit low
1 = int when nInputBit high
Label Label to jump to on interrupt.
INT 1,1,0,0,:turnoff ;Interrupt on board 1, input 0. Jump to :turnoff when input
;bit 0 goes from high to low. Abort all motion
INT 1,4,8,1,:exit ;Interrupt on board 1, input 8. Jump to :exit when input bit
;8 goes from low to high
INT 1,0,10 ;turn off int for board 1, input 10
IOport value
IOport bit#, 0/1,...
port Bank of 8 X 3 I/O connector, 0-2.
value Specifies the 8 bit output data 0-255 or 0xFF.
bit# Specifies the bit number that is affected.
IO0 0,1,1,1,2,0 ;Set bits 0 and 1 to 1, bit 2 to 0 of port 0
