13. Retries, rearbitrate and abort
Retries and rearbitrate commands are located, respectively, in the Transmit Control Register and in the Command
Register. An abort command is located in each channel register set, in the Message Length & Status Register
(base_address + 0x03). These three commands are available only when the TSS461C is producer.

Figure 25. Transmit function
13.1. Retries
The purpose of retries feature is to provide, for the user, 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 count-down. To 0, an IT TE is set in the Interrupt Status Register (0x09), and the transmission is
stopped.
