3 egress LP through the ADD_PAR_ERR bit field. The LP affected by the
ADD_PAR_ERR bit field is enumerated in the PORT_ADDRESS field.
egress LP through the DAT_PAR_ERR bit field. The LP affected by the
DAT_PAR_ERR bit field is enumerated in the PORT_ADDRESS field.
the DAT_PAR_ERR bit fields is enumerated in the PORT_ADDRESS field. The
value of the PORT_ADDRESS is set from 0x00 to 0xFF.
SPI-3 egress fill level register (Block_base 0x0700
+ Register_offset 0x03)
Each register has read-only access. The bit fields of the SPI-3 egress fill level
register are described.

SPI-3 egress max fill level register (Block_base
0x0700 + Register_offset 0x04)
register has read-only access, and is cleared after reading. 0xF is the highest
filling level, meaning all egress buffers had been full at some time since the last
read of the FILL_MAX field. The units of FILL_MAX are one-sixteenth of the
available egress buffering. Each unit is equal to 128 bytes. The bit field of the
SPI-3 egress max fill Level register is described.
