Can a baud rate higher than 5Mbps be achieved on the SCI peripheral of the TMS320F2806X device series. According to the Peripheral Reference Guide (http://www.ti.com/lit/ug/spruh18b/spruh18b.pdf) the asynchronous baud rate can be found by LSPCLK/( (BRR + 1) x 8 ), where BRR is a 16 bit value.
It appears that LSPCLK can be 40 MHz at the most (this figure is sourced from the same document under the SPI module). If the 16 bit BRR value is then set to 0, the maximum baud rate would be 5Mbps. Is this correct?
The idea is to connect several devices using RS 485 and achieve a throughput of at least slightly over 10Mbps. Can this still be done despite UART's limitations? Anyone aware of specific application notes/reference designs for TMS320F2806x and RS 485?
Another question, can the eQEP be used for absolute encoders? Can the value of number of rotations found from QEPI signal be stored in such a way that on power off it is recovered ?
