Hi,
has anyone got the "TXRTS" feature working on the Freescale MPC5200? I
need that to use PSC6 for RS485.
I've tried some hints I found in a thread starting here:
http://article.gmane.org/gmane.comp.hardware.motorola.microcontrollers.coldfire/6225
but no luck, so far.
I got it working by manually asserting and negating RTS through OP1/OP0,
and waiting for the TX_FIFO_EMPTY bit, but I really want to use the
TXRTS feature, which _should_ deassert RTS automatically one bit-time
after the last bit is shifted out.
Thanks,
Stefan E.
