Method Detail

write

public void write(byte val)
Description copied from class: RWRegister
The write() method writes an 8-bit value to the IO register as a byte. For simple RWRegister instances, this simply writes the internally stored value.

Specified by:
write in interface ActiveRegister
Overrides:
write in class RWRegister
Parameters:
val - the value to write

writeBit

public void writeBit(int bit,
                     boolean val)
Description copied from class: RWRegister
The writeBit() method writes a single bit value into the IO register at the specified bit offset. For simple RWRegister instances, this simply updates the bit in the internally stored value

Specified by:
writeBit in interface ActiveRegister
Overrides:
writeBit in class RWRegister
Parameters:
bit - the number of the bit to write
val - the value of the bit to write
