TMA
Receive Direction
General Features
In the receive direction
– a slot synchronous transparent data reception
– a ‘1’ overwrite for masked bits in the slot
– for FA = ‘1’ a slot synchronous programmable flag extraction
is performed automatically.
Options
The different options for this mode are:
– the programmable character TC to be extracted for FA = ‘1’ is TFLAG. For FA = ‘0’
Interrupts
The possible interrupts for the mode in receive direction are:
HI:
ERR: issued if a fast receive abort channel command was issued.
FO: issued if data could only partially stored due to internal buffer overflow of RB.
Example 1:
(no subchanneling)
TMA channel with
User’s Manual
nothing is extracted. If subchanneling is chosen (not all fill/mask bits of the channel
are ‘1’) FA must be set to ‘0’.
TFLAG = D7
INV = 0
CRC = 0
TRV = 00
FA = 1
MODE = 00
IFTF = 0
Motorola interface
Channel No. E
issued if the HI bit is detected in the receive descriptor (not maskable).
(maskable by RE in the channel spec.)
