Data Sheet
TOLEN
(6..0)
CRL
C32
Time Out Length
This bit field determines the time out period. If there is no receive line
activity for the configured period of time, a time out indication is
generated if enabled via bit ’TOIE’.
The period of time is programmable in multiples of character frame
length (CFL) time equivalents including start, parity and stop bits:
TOLEN
CRC Reset Value
This bit defines the initial value of the internal transmit/receive CRC
generators:
CRL=’0’
CRL=’1’
CRC 32 Select
This bit enables 32-bit CRC operation for transmit and receive.
C32=’0’
C32=’1’
Note: The internal ’valid frame’ criteria is updated depending on the
selected number of CRC-bytes.
T = ((TOLEN + 1) * 4) * CFL
Initial value is 0xFFFF
(32 bit CRC).
Default value for most HDLC/SDLC applications.
Initial value is 0x0000
(32 bit CRC).
16-bit CRC-CCITT generation/checking.
32-bit CRC generation/checking.
