Sorry,
If you would work in C language, maybe I could respond to you, because I use
SCI ports under interrupt, but in assembly code, I can't...
Best regards.

Objet : [68HC12] MC9S12DP512 Software Interrupt
My program is executing a hardware interrupt reading the serial keypad and I
want to turn on the display which uses the same serial port and interrupt
service routine. Trying to generate a transmit interrupt before the receive
rti instruction executes causes the system to hang up. Is there any way to
implement a software interrupt so that after the serial receive hardware
interrupt finishes the software interrupt will then use the serial
transmitter to turn on the display? My programming is in assembly code.
