This register provides the receive SBI, SPE and link number used to access the SBI EXTRACT
tributary control configuration RAM.
TRIB[4:0], SPE[1:0] and SBI:
Reserved
RWB
The TRIB[4:0], SPE[1:0] and SBI fields are used to fully specify to which SBI tributary the
Control register write or read operation will apply.
TRIB[4:0] specifies the SBI tributary number within the SBI SPE as specified by the SPE[1:0]
and SBI fields. Legal values for TRIB[4:0] are b’00001’ through b‘11100’. Legal values for
SPE[1:0] are b’01’ through b‘11’. SBI must be written to a logic one in the FREEDM
32A1024L device.
The reserved bits must be set low for correct operation of the FREEDM 32A1024L device.
The indirect access control bit (RWB) selects between a configure (write) or interrogate (read)
access to the tributary control configuration RAM. Writing a ‘0’ to RWB triggers an indirect
write operation. Data to be written is taken from the SBI EXTRACT Tributary Indirect Access
Data Register. Writing a ‘1’ to RWB triggers an indirect read operation. The data read can be
found in the SBI EXTRACT Tributary Indirect Access Data Register.
