Retries,
Rearbitrate and
Abort
Retries and rearbitrate commands are located, in the Transmit Control Register and in the Com-
mand Register, respectively. An abort command is located in each channel register set, in the
Message Length & Status Register (base_address + 0x03). These three commands are avail-
able only when the TSS461F is producer.
Figure 25.
Transmit Function
Retries
The purpose of retries feature is to provide, the capability of retrying a transmit request in case
of failure, when a node tries to reach another node, either on normal DATA frame or on REPLY
REQUEST frame.
The maximum of retries is programmable through MR[3:0] of the Transmit Control Register
(0x01). When a channel is enable – bit CHTx= 0 of Message Length & Status Register, a 4-bit
counter is loaded with MR[3:0]. At each attempt, this counter will be countdown. To 0, an IT TE
is set in the Interrupt Status Register (0x09), and the transmission is stopped.
MR[3:0] = 1 indicates 1 retry, hence 2 transmission attempts will be performed (see Table 4).
The number of retries performed, as well as the current channel number associated, can be
read in the Transmission Status Register (0x05).
The Last Error Status Register (0x07) informs about the trouble encountered:
