SIO
AND COMMAND
A
DDRESSING ALL SIX OUTPUT LINES WITH ONE
SIO
COMMAND
:
Proceed as follows:
-
Set the type parameter to 255 and the bank parameter to 2.
-
The value parameter must then be set to a value between 0…255, where every bit represents one
output line.
-
Furthermore, the value can also be set to -1. In this special case, the contents of the lower 8 bits of
the accumulator are copied to the eight output pins.
Example:
Set all output pins high.
Mnemonic:
SIO 255, 2, 255
T
HE FOLLOWING PROGRAM WILL SHOW THE STATES OF THE EIGHT INPUT LINES ON THE OUTPUT LINES
:
Loop: GIO 255, 0
SIO 255, 2,-1
JA Loop
A
DJUSTING THE ANALOGUE INPUT
:
It is possible to adjust the analogue input with the following commands:
SIO 8, 0, 0 for 3,3V input range
SIO 8, 0, 1 for 10V input range
C
OMMAND FOR SWITCHING THE PULL
-
UP RESISTORS FOR ADDITIONAL DIGITAL INPUTS
SIO can be used to switch the pull-up resistors for all digital inputs on and off. Bank 0 is used for this
purpose. Every pull-up resistor can be switched individually by setting the related bit using the bitmask.
