Write operation: 
The digital output states are written as 1 single byte to the port at 
address BASE+N (N=0,1,2,3). Data is written to all 8 bits as a single 
byte. 
For example: 
In BASIC: 
05 BASE=&H2A0 
06 VALUE1% = &H3F 
07 VALUE2% = &HF3 
10 OUT(BASE + 0), VALUE1% ‘ the digital outputs (DO0-DO7) will’ 
be (00111111) 
20 OUT(BASE + 2), VALUE2% ‘ the digital outputs (DO16 - DO23) 
will be (11110011)
