User’s Manual
Interrupts
The possible interrupts for the mode in receive direction are:
HI:
FI:
ERR: issued if one of the following error conditions has occurred
FO: issued if due to inaccessibility of the internal buffer RB one or more complete
Example:
TMB channel with
INV = 0
CRC = 0
TRV = 00
FA = 0
MODE = 01
IFTF = 0
MFL = 7
Motorola interface
Channel No. A
issued if HI bit is detected in the receive descriptor (not maskable).
issued if a received frame has been finished as discussed in 1b) of the protocol
features or a receive abort channel command was detected during reception of a
frame.
(maskable by FIR in the channel spec.)
– the bit length of the frame was not divisible by 8
– the byte length was greater than MFL
– the frame could only be partly stored because of internal buffer overflow of RB
– a fast receive abort channel command was issued
– the frame could only be partly transferred due to a receive descriptor with set
frames have been lost. (maskable by RE in the channel spec.)
HOLD bit.
(maskable by RE in the channel specification)
