Bit5
INV LOSI: Inverts the buffered input pin LOSI to output pin D0 if MUX LOSI is set. If MUX LOSI is not
set then this bit’s value is a don’t care.
0 = (Default) noninverted LOSI to D0 pin.
1 = Inverted LOSI to D0 pin.
Bit4
MUX LOSI: chooses the control for D0 output pin.
0 = (Default) DO is controlled by bit D0 OUT found in Lower Memory, Register 78h.
1 = LOSI is buffered to D0 pin.
Bit3
D3 CNTL: At power-on, this value is loaded into bit D3 OUT of Lower Memory, Register 78h to
control the output pin D3.
Bit2
D2 CNTL: At power-on, this value is loaded into bit D2 OUT of Lower Memory, Register 78h to
control the output pin D2.
bit1
D1 CNTL: At power-on, this value is loaded into bit D1 OUT of Lower Memory, Register 78h to
control the output pin D1.
bit0
D0 CNTL: At power-on, this value is loaded into bit D0 OUT of Lower Memory, Register 78h to
control the output pin D0.
