Hi All
According to the Data Manual of the TMS320F2801, transmission rate for the master and slave are different than each other(one of them is LPSCLK/4 and the other is LPSCLK/8 ), however in the SPI reference guide both have the same MAX transmission rate (LPSCLK/4).

"Internal clock prescalers must be adjusted such that the SPI clock speed is limited to the following SPI clock rate:
Master mode transmit 25-MHz MAX, master mode receive 12.5-MHz MAX
Slave mode transmit 12.5-MHz MAX, slave mode receive 12.5-MHz MAX."

"The SPI is no longer limited to a maximum transmission rate of LSPCLK/8 in slave mode.
The maximum transmission rate in both slave mode and master mode is now LSPCLK/4."
So which one is true?
Any idea?
