SPI-3 egress max fill level register (Block_base
0x0700 + Register_offset 0x04)
TABLE 59 - SPI-3 EGRESS MAX FILL LEVEL REGIS-
TER (REGISTER_OFFSET=0x04)
The 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.
