Table 79 - Receive Loop Deactivate code Match Register (R/W Address YF0)
not used
Receive Loop Deactivate Code Length. These 2 bits define the length of the receive loop up
code.
00-Code length is 5 bits
01-Code length is 6 or 3 bits
10-Code length is 7 bits
11-Code length is 8 or 4 bits
Note: if 3 bit code or 4 bit code is required the bits have to be repeated in RXLACM7-0. For
instance if the code 1011 is desired the RXLACM has to be set to 10111011 and the RXLACL to
11. In case of the 3 bit code the 2 most significant bits of RXLACM are ignored.
Receive Loop Deactivate Code Match.This byte specifies the match code for the receive
loopback activate code. A maskable interrupt can be generated if the loopback activate code
message is received. This byte is compared to RXLAC.
The default values are the T1.403 values for Loop Activate Code.
