CELLXFERRI
PARERRI
CELLXFERRI:
The Cell Transfer Error Interrupt Status (CELLXFERRI) read only register bit
reports the current status of the interrupt for invalid start of cell. When TSX is
asserted when not expected, an interrupt is generated. The interrupt is reset
when this register is read.
The same event that asserts this bit may also result in a corrupted cell being
transmitted on a high-speed serial link.
PARERRI:
The Parity Error Interrupt Status (PARERRI) read only register bit reports the
current status of the interrupt for invalid parity over the input data bus. When
a parity error occurs over the TDAT[15:0] data bus, an interrupt is generated.
The interrupt is reset when this register is read.
