I am putting the TMS320vc5505 on a board, it says on the product page it has a UART. In the datasheet it says it has a UART, but also in the datasheet on page 60 section 6.4.2 it says:
UART is currently not supported on this device
What should I believe?
A LVCMOS-compatible clock input of a frequency less than 24 MHz can be fed into the CLKIN pin for use
by the DSP system clock generator. The external connections are shown in Figure 6-4 and Figure 6-5.
The bootloader assumes that the CLKIN pin is connected to the LVCMOS-compatible clock source with a
frequency of 11.2896-, 12.0-, or 12.288-MHz. These frequencies were selected to support boot mode
peripheral speeds of 500 KHz for SPI, 400 KHz for I2C, and 57600 baud for UART (UART is currently not
supported on this device). These clock frequencies are achieved by dividing the CLKIN value by 25 for
SPI, by 32 for I2C, and by 208 for UART. If a faster external clock is input, then these boot modes will run
at faster clock speeds. If the system design utilizes faster peripherals or these boot modes are not used,
CLKIN values higher than 12.288 MHz can be used. Note: the CLKIN pin operates at the same voltage as
the DVDDIO supply (1.8-, 2.5-, 2.8-, or 3.3-V).
