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.
