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
