Programming Information
IDT82P2284
Bit Name
Bit Name
= 0: Disable the interrupt on the INT pin when the RCOFAI bit (b1, E1-04BH,...) is ‘1’.
= 1: Enable the interrupt on the INT pin when the RCOFAI bit (b1, E1-04BH,...) is ‘1’.
= 0: Disable the interrupt on the INT pin when the TCOFAI bit (b0, E1-04BH,...) is ‘1’.
= 1: Enable the interrupt on the INT pin when the TCOFAI bit (b0, E1-04BH,...) is ‘1’.
= 0: The data stream is received in framed mode and is processed by the Frame Processor.
= 1: The data stream is received in unframed mode and the Frame Processor is bypassed.
= 0: disable from re-searching for synchronization when the Excessive CRC-4 Error occurs.
= 1: Search for synchronization again when the Excessive CRC-4 Error occurs. This function can only be implemented only if the REFEN bit is
logic 1.
= 0: “Locked in frame”. Once the previous Basic frame synchronization is acquired, and no errors can lead to reframe except for manually setting
by the REFR bit.
= 1: Search for Basic frame synchronization again when it is out of synchronization.
A transition from logic 0 to logic 1 forces to re-search for a new Basic frame synchronization.
