Register 0x608: TAPI Indirect Channel Data Register
The TAPI Indirect Channel Data Register contains data read from the TAPI-12 channel provision
RAM after an indirect read operation or data to be written to channel provision RAM in an
indirect write operation.
BLEN[7:0]
The channel burst length (BLEN[7:0]) bits report the data transfer burst length read from the
TAPI-12 channel provision RAM after an indirect read operation has completed. The data
transfer burst length specifies the length (in bytes, less one) of burst data transfers on the
transmit APPI that are not terminated by the assertion of TEOP. The data transfer burst
length can be specified on a per-channel basis. The data transfer burst length to be written to
the channel provision RAM in an indirect write operation must be set up in this register
before triggering the write. BLEN[7:0] reflects the value written until the completion of a
subsequent indirect read operation. The following values of BLEN[7:0] are valid:
