This register allows identification and acknowledgment of pointer event interrupts.

NDFI:

The NDFI bit is the new data flag interrupt status bit. NDFI is set to a logic one when the NDF field is active in the received pointer (H1, H2). This bit is cleared when this register is read.

PSEI:

The PSEI bit is the positive stuff event interrupt status bit. PSEI is a logic one when a positive stuff event is detected in the received pointer (H1, H2). This bit is cleared when this register is read.

NSEI:

The NSEI bit is the negative stuff event interrupt status bit. NSEI is a logic one when a negative stuff event is detected in the received pointer (H1, H2). This bit is cleared when this register is read.

ILLPTRI:

The ILLPTRI bit is the illegal pointer interrupt status bit. ILLPTRI is a logic one when an illegal pointer value is detected. This bit is cleared when this register is read.

INVNDFI:

The INVNDFI bit is the illegal new data field value interrupt status bit. INVNDFI is a logic one when an illegal NDF field value is detected in the receive payload pointer. An illegal NDF field is any one of the following six values: 0x0, 0x3, 0x5, 0xA, 0xC, and 0xF. This bit is cleared when this register is read.
