Register 0x404: TCAS Indirect Context RAM Data
This register provides the link enable bit and the frame mode or data type associated to this
particular link in the TCAS context RAM.
SYNC
SBI_MODE[2:0]
LEN
The SYNC bit determines whether the link is operating in synchronous mode or
asynchronous mode. When set low the link is set to asynchronous mode. When set high the
TCAS will to synchronize the link output data according to the synchronous mode
requirements of the SBI bus. This bit only applies to framed T1 or E1 links.
The Frame Mode bits (SBI_MODE [2:0]), report the type of data to a specific link to be
configured accordingly according to the table below.
Table 22 SBI Mode
The Link Enable bit (LEN) when set Low disables the link. If enabled, the corresponding
serial link must be disabled by clearing the appropriate SLINK[n] bit in register 0x414.
