Checking TRMT pin in TXSTA register

[severnml]

I'm trying to use the USART on an 18F452 at its maximum speed (2.5 Mbps), and am thus trying to avoid function calls while managing it. Is there a simple way to directly poll the TRMT pin <1> in the TXSTA register to see when the buffer's empty? Thanks!

Use the CCS #bit statement to declare the register address of the TXSTA
register and bit number of the TRMT bit. Then access the TRMT bit
directly by name, in your code.

Look up the register address and bit number in the data sheet.
