APPENDIX E : TIMINGS
TIME−OUT VALUES
The values of the AMIS−49587 constant timings are listed below:
Table 47. TIME−OUT VALUES
Time−out
Meaning
Tpoll
Delay max. awaited by the base micro between the T_REQ pull down and the status
message transmission (delay polling)
Tsr
Delay max. awaited by the AMIS−49587 between the end of the status transmitting and
the reception of the STX character in the base micro frame (delay status/reception)
Tack
Delay max. awaited by either the AMIS−49587 or the base micro between the end of a
transmitting and the reception of the ACK or NAK character sent by the other (delay
ack).
Twbc
Delay max. awaited by either the AMIS−49587 or the base micro between the end of a
reception and the transmission of the next frame (delay waiting before continue).
Bit 7 = 1
Delay max. awaited by either the AMIS−49587 or the base micro
Tic
between two characters (delay inter characters)
Programmable with the bit 7 of repeater parameter in the
configuration frame
Bit 7 = 0
