Register 0x69C: SBI INSERT Tributary Indirect Access Data
This register contains data read from the SBI INSERT tributary control configuration RAM after
an indirect read operation or data to be written to the tributary control configuration RAM in an
indirect write operation.
ENBL
Reserved
TRIB_TYP[1:0]
CLK_MSTR
The ENBL bit is used to enable the Tributary. Writing to an Insert Tributary Control and
Status RAM location with the ENBL bit set enables the INSBI to take tributary data from an
SBIIP link and transmit that data to the SBI tributary for that link.
The reserved bit must be set low for correct operation of the FREEDM 84A1024L device.
The TRIB_TYP[1:0] field is used to specify the characteristics of the SBI tributary as shown
in Table 30 below:
Table 30 TRIB_TYP Encoding
The CLK_MSTR bit configures the SBI tributary to operate as a timing master or slave.
Setting CLK_MSTR to 1 configures the tributary as a timing master (AJUST_REQ input
ignored). Setting CLK_MSTR to 0 configures the tributary as a timing slave (requests on
AJUST_REQ honored).
