Digital Outputs in Bank 2
Port Command Range
OUT0 SIO 0, 2, <value> 0/1
OUT1 SIO 1, 2, <value> 0/1
Special case: SIO 255, 2, <x> can be used to change all general purpose digital output lines simulaneously.
The value <x> will then be interpreted as a bit vector where each of the lower eight bits represents one of
the digital outputs. So the range for <x> is 0. . . 255. The value <x> can also be -1. In this case, the value will
be taken from the accumulator register. The following program can be used to copy the states of the input
lines to the output lines:
1
Loop:
GIO 255, 0
3
SIO 255, 2, -1
JA Loop
Pull-up Resistor Control
The SIO command can also be used to program the pull-up resistors of the STOP_L, STOP_R and HOME
inputs. All three pull-up resistors can seperately be switched o or on. For this purpose, use the command
SIO 0, 0, <x> where the value <x> is a bit vector. The following table shows the meaning of the dierent
bits:
Pull-up Resistor Control
Bit Value Input
0 1 STOP_L
1 2 STOP_R
2 4 HOME
A bit that is set switches on the corresponding pull-up resistor. So for example SIO 0, 0, 0 turns o all
pull-up resistors, and SIO 0, 0, 7 turns on all pull-up-resistors. All pull-up resistors are on by default.
