are = x x x x x GIO0 SW0 XSW)
<LRC>
xxH
I/O Mode Modify
<ESC>
1BH
<MODIO>
A7H
<IO NUMBER>
xxH IO number: 0
<IO MODE>
xxH IO mode: ( 0=input, 1=output,
2=switch, 3=LED, 4=current mode state
request)
<LRC>
xxH
When UR5HCSPI-06 receives this command, it will change the I/O pin's
mode accordingly. If the <IO MODE> =4, the UR5HCSPI-06 will send the
I/O Mode Status Report to the host.
Output Data to I/O Pin:
<ESC>
1BH
<MODIO>
A8H
<IO NUMBER>
xxH IO number: 0
<IO DATA>
xxH IO data: ( 0=low, 1=high, 2=current
I/O data request)
<LRC>
xxH
When UR5HCSPI-06 receives this command, it will change the value of the
output pin accordingly. If the addressed pin is not configured as an output
pin, the command will be ignored. If <IO DATA> =2, the UR5HCSPI-06 will
respond by issuing the I/O Data Status Report to the host.
The "Set Wake-Up Keys" command
is used to disable specific keys
from waking up the host. Using this
command, the host can set only a
group of keys. For this IC, data in
bytes <COL12> and <COL 13> is
not relevant, but these two bytes
must be present in the packet in
order to preserve the packet
structure.
