The RXPHY Calendar Indirect Address Data register is an indirect address and data register. The
register is used in POS mode of operation
CALENDAR_DATA[5:0]
The CALENDAR_DATA register is provided to program the PHY address number to be
serviced in the calendar sequence. The calendar consists of a maximum of 128 entries
where the CALENDAR_ADDR is used to access one of the 128 (or less) entries to either
write or read CALENDAR_DATA. CALENDAR_DATA is the PHY address to be serviced
during the sequence associated with CALENDAR_ADDR. The length of the calendar is set in
the RXPHY Calendar Length register. For the S/UNI-2488, this register should be set to all
zeros.
CALENDAR_ADDR[6:0]
The CALENDAR_ADDR register is an indirect address register that is used with
CALENDAR_DATA register. The two registers together allow indirect address reads and
writes using a small amount of external address space. The CALENDAR_ADDR is used with
CONFIG_RWB and BUSY to command reads and writes.
