Latch Logic Commands

Overview

The custom logic editor uses the following latch commands:

• LATCH

• LATCH_NV

LATCH

The LATCH command:

• Stores a Boolean value (0 or 1) in a temporary register

• Provides a method for setting and resetting the stored value

• Saves the clear and set status from the previous scan

LATCH_NV

The LATCH_NV command:

• Stores a Boolean value (0 or 1) in a non-volatile register

• Provides a method for setting and resetting the stored value

• Saves the clear and set status from the previous scan

Use the LATCH_NV command, instead of the LATCH command, to retain the latch state during a power cycle.
