BIT 7
INV M3QT: Inverts the internal M3QT signal to output pin D2 if MUX M3QT is set. If MUX M3QT is
not set, this bit’s value is a don’t care.
0 = (Default) Noninverted M3QT to D2 pin.
1 = Inverted M3QT to D2 pin.
BIT 6
MUX M3QT: Chooses the control for D2 output pin.
0 = (Default) D2 is controlled by bit D2 IN found in byte 79h.
1 = M3QT is buffered to D2 pin.
BIT 5
INV LOS: Inverts the buffered input pin LOSI to output pin D0 if MUX LOS is set. If MUX LOS is
not set, this bit’s value is a don’t care.
0 = (Default) Noninverted LOSI to D0 pin.
1 = Inverted LOSI to D0 pin.
BIT 4
MUX LOS: Chooses the control for D0 output pin.
0 = (Default) DO is controlled by bit D0 IN found in byte 79h.
1 = LOSI is buffered to D0 pin.
BIT 3
D3 CNTL: At power-on, this bit’s value is loaded into bit D3 OUT of byte 78h to control the output
pin D3.
0 = (Default)
BIT 2
D2 CNTL: At power-on, this bit’s value is loaded into bit D2 OUT of byte 78h to control the output
pin D2.
0 = (Default)
BIT 1
D1 CNTL: At power-on, this bit’s value is loaded into bit D1 OUT of byte 78h to control the output
pin D1.
0 = (Default)
BIT 0
D0 CNTL: At power-on, this bit’s value is loaded into bit D0 OUT of byte 78h to control the output
pin D0.
0 = (Default)
Controls the power-on values for D3, D2, D1, and D0 output pins and mux and invertion of the LOSI pin.
