hal_write_bus

Write single byte to data bus. The provided parameters are combined as follows to form the output byte value:
        output value = (data & wAND) ^ wXOR
To write the value to the address without modification, set wAND=0xFFFF and wXOR=0x0000

void hal_write_bus ( unsigned short adr, unsigned char value,
                     unsigned short wAND,unsigned short wXOR );

Parameters

adr

I/O Address

value

Value to be output

wAND

Mask applied to output

wXOR

Output bit inverter

Return Value
