====== portBlockOut ======

''void portBlockOut (u8 portBlockNumber, u8 value)''
|portBlockNumber : Port block number (0 through 5) | 
|value : 0 through 255 |

Sets the output state of all ports in the given port block, portBlockNumber. value is a bit array
corresponding to the 8 individual ports in the port block. If portBlockNumber were 1, value's bit 0 would
correspond to port 10 and value's bit 7 would correspond to port 17.

<code c>
portBlockOut(1,7);    // Ports 10-12: ON, Ports 13-17 OFF, (7 = b0000 0111 )
</code>

The following program will copy all the outputs read from an input module in slot 0 (DIO +0) to the output module in slot 1 (DIO + 10).
<code c>
#include "moacon500.h"

void cmain()
{
    portInit(0, 1); // Input module in slot 0
    portInit(1, 0); // Output module in slot 1
    
    while(1)
    {
       u8 state = portBlockIn(0);  // Read all 8 inputs
       portBlockOut(1, state);     // Copy input state to outputs
    }
}
