exceeds the length of the data buffer, the BISYNC controller will fetch the next BD in the
table and, if it is empty, will continue to transfer data to this BD’s associated data buffer.
When a BCS is received, it is checked and written to the data buffer. The BISYNC controller
sets the last bit, writes the message status bits into the BD, and clears the E-bit. Then it gen-
erates a maskable interrupt, indicating that a block of data has been received and is in mem-
ory. Note that the SYNCs in the non-transparent mode or DLE-SYNC pairs in the
transparent mode (i.e., an underrun condition) are not included in the BCS calculations.
7.10.20.4 BISYNC MEMORY MAP. When configured to operate in BISYNC mode, the
QUICC overlays the structure listed in Table 7-5 with the BISYNC-specific parameters
described in Table 7-9.
PRCRC and PTCRC. These value should be preset to all ones or all zeros, depending on
the BCS used.
PAREC. This 16-bit (modulo 2
the user while the channel is disabled. The counter counts parity errors on receive if the par-
ity feature of BISYNC is enabled.
