Tool/software:
Hello Experts,
I have three questions. Can you please answer them?
- Does F28P65 UART output support Manchester coding?
- Does F28P65 UART output support QPSK?
- In standard UART, there are 8 bits between Start bit and Stop bit as follows. Does F28P65 UART support only this? Or does it support more than 8bit such as 200 bits between Start bit and Stop bit? 
Best regards,
Ken
Hi Ken,
On the F28P65x we have both the SCI and the UART module (both using the UART protocol). The below answers are assuming the UART module is being used (however for SCI the answers are similar - there is no Manchester or QPSK mode available, and 8-bits is also the maximum number of data bits).
- Does F28P65 UART output support Manchester coding?
- Does F28P65 UART output support QPSK?
No, the UART module only supports the standard NRZ format, or the SIR protocol when the SIR mode is enabled. There is also a configurable 9-bit mode to support multi-processor topologies, but this still operates in NRZ format.
- In standard UART, there are 8 bits between Start bit and Stop bit as follows. Does F28P65 UART support only this? Or does it support more than 8bit such as 200 bits between Start bit and Stop bit?
The UARTLCRH.WLEN register field can be configured to any length between 5 and 8 bits. So, 8-bits would be the maximum that can be configured between the start and end bits for this module.
