DIS_BCAST: Disable the reception of broadcast packets.
ARXRST: Asynchronous receiver reset. This bit will auto clear when the link layer state machine is idle.
ATXRST: Asynchronous transmitter reset
ARXALL: Receive and filter only RESPONSE packets. When set (1), all responses are stored. When clear (0), only
solicited responses are stored.
MAXRC: Maximum number of asynchronous transmitter single phase retries
TOS: Time out seconds, integer of 1 second of the split transaction time out timer. Resets to “000”. This timer is set
to the maximum amount of time the transmitter will wait for a pending response before the transmitter will begin
transmitting the next available request packet. Also see TOF bits of this timer.
TOF: Time out fractions, integer of 1/8000 second. Resets to 0320h, which is 100 milliseconds. During the timeout of
the split transaction timer, subsequent split transactions are blocked. If it is desired to transmit multiple split
transactions this can be accomplished by following this procedure: (1) set the split transaction timer value to “0”, (2)
disable the split time–out interrupt (TIMEOUT, bit 7 in register 0x0A0); (3) clear (set to “0”) the unsolicited response
filter bit (ARXALL, bit 20 in register 0x080). Now use tLabels (transaction Labels, see section 12.5.1) to pair
transmitted packets with received packets. Use software timers to time–out the subsequent pending responses.
