The flash reading will takes some time that cuases the TX8 delay.Time taken by the user module should be (x*9/19200)+ (11*x/24M).When the CPU clock is 24MHz.Note: The ROMX is used read the flash and please refer the assembly guide for the time required to execute the ROMX instruction.
Thanks,

I don't understand your question well. It takes more time than you expect to Xmit one byte (not the expected baud rate)? OR- The ROMX instruction takes too long and there's a long wait from the time one byte is finished with being transmitted until the next is started to transmit.
ROMX is very slow.

I am not quite sure, but what is the question asked?

Looks like an explanation of why UART data sourced from FLASH compromises
allowable UART datarate vs from RAM, posted as a fun FAQ from a Cypress
employee.
