POWER-ON VALUE
READ ACCESS
WRITE ACCESS
MEMORY TYPE:
At power-on, these bits are defined by the value stored in the DPU byte (Table 02h, Register C0h).
These bits define the value of the logic states of their corresponding output pins.

INV LOSI: Allows for inversion of LOSI pin to D0 pin. MUX LOSI bit must be set to 1 or this bit does
not affect the output. This bit is controlled (or set) by the DPU byte (Table 02h, Register C0h).
1 = LOS buffered OUT
MUX LOSI: Determines control of D0 pin. This bit is controlled (or set) by the DPU byte (Table 02h,
Register C0h).
0 = Logic value of D0 is controlled by DOUT byte.
1 = Logic value of D0 is controlled by LOSI pin and INV LOSI bit.
D3 IN: Reflects the logic value of D3 pin.
D2 IN: Reflects the logic value of D2 pin.
D1 IN: Reflects the logic value of D1 pin.
D0 IN: Reflects the logic value of D0 pin.
