28 DO
Outputs to parallel port or acquires the output status
Format
1. LET DOm (b,···,b) =expression
2. LET DO (mb,···,mb) =expression
Values m: port number .....................
b: bit definition ...................... 2 to 7, 10 to 17, 20 to 27
0 to 7 (If omitted, all 8 bits are processed.)
If multiple bits are specified, they are expressed from the
left in descending order (high to low).
Explanation Outputs the specified value to the DO port.
No output will occur if a nonexistent DO port is specified.
Outputs are not possible to DO0() and DO1(). These ports are for referencing only.
SAMPLE
DO2() = &B10111000 ·············· DO (27, 25, 24, 23) are turned ON, and
DO (26, 22, 21, 20) are turned OFF.
DO2(6,5,1) = &B010 ·············· DO (25) are turned ON, and DO (26, 21)
are turned OFF.
DO3() = 15 ····················· DO (33, 32, 31, 30) are turned ON, and
DO (37, 36, 35, 34) are turned OFF.
DO(37,35,27,20) = A ············· The contents of the 4 lower bits
acquired when variable A is converted
to an integer are output to DO (37,
35, 27, 20) respectively.
