Register 0x580: RAPI Control Register
The Control Register is used to set the operating mode of RAPI-12. It is used to configure the final
word of a packet in APPI. It is also used to enable the RAPI-12.
ALL1ENB
ANYPHYL
Reserved
The All Ones Enable bit (ALL1ENB) is used to configure the device address space of the
RAPI-12 in level-2 APPI. It is not used in level-3 APPI. When ALL1ENB is high in level-2
APPI, the all ones address (RXADDR[3:0] = “1111”) is reserved as null address to resolve
contention for Any-PHY bus, and it can not be assigned to any RAPI-12. When ALL1ENB is
low in level-2 APPI, the all ones address is not treated as null address, and it can be assigned to
one RAPI-12; contention for Any-PHY bus must be resolved by external logic.
The ANY PHY Level select bit allows selection between ANY PHY Level 2 and ANY PHY
Level 3.
Table 21 Any-PHY Encoding
The reserved bit must be set low for correct operation of the FREEDM 32A1024L device.
