Hardware Description
RFIFO3 Threshold Level - HDLC Channel 3
The size of the accessible part of RFIFO3 can be determined by
programming these bits. The number of valid bytes after an RPF
interrupt is given in the following table:
RFT13
0
0
1
1
The value of RFT13/03 can be changed dynamically if reception is not
running or after the current data block has been read, but before the
command CMDR4.RMC3 is issued (interrupt controlled data
transfer).
Note:These bits are only valid, if SS7 mode of HDLC channel 1 is
