R/W

Read/Write Mode Select

When R/W = 0, a write operation is performed.

When R/W = 1, a read operation is performed.

Default Value: 0

INC

Auto-Increment Read Control

This bit is Read/Write.

Default Value: 0

INC = 0

Auto-Increment Read Disabled (default)

INC = 1

Auto-Increment Read Enabled

The INC bit is used to enable or disable the Auto-Increment Read feature of the Serial Control Interface. Refer

to the Serial Control Interface section of this data sheet for details regarding Auto-Increment Read operation.

REG[6:0]

Read Register Index

These bits are Read/Write.

The REG[6:0] bits are used to set the index of the register to be read when performing the Single Register Read

operation. In the case of an Auto-Increment Read operation, the REG[6:0] bits indicate the index of the last

register to be read in the Auto-Increment Read sequence. For example, if Registers 1 through 6 are to be read

General-Purpose Logic Output

Where: x = 1 through 6, corresponding pins GPO1 through GPO6.

These bits are Read/Write.

Default Value: 0

GPOx = 0

Set GPOx to “0”

GPOx = 1

Set GPOx to “1”

The general-purpose output pins, GPO1 through GPO6, are enabled by setting GPOE = 1. These pins are used

as general-purpose outputs for controlling user-defined logic functions. When general-purpose outputs are

disabled (GPOE = 0), they default to the zero-flag function, ZERO1 through ZERO6.

GPOE

General-Purpose Output Enable

This bit is Read/Write.

Default Value: 0

GPOE = 0

General-Purpose Outputs Disabled

Pins default to zero-flag function (ZERO1 through ZERO6).

GPOE = 1

General-Purpose Outputs Enabled

Data written to GPO1 through GPO6 will appear at the corresponding pins.
