TouCAN -- first Tx interrupt?

2002-12-11 by jeffrey.tenney@gm.com

Anybody know of a way to transmit your "first" CAN frame under interrupt
control using the TouCAN?  My transmit code is in the interrupt handler,
but the TouCAN apparently won't give me a transmit interrupt until I've
transmitted something.  It's a catch-22.  The book says I can't set a flag
in the IFLAG register manually.  And, I'd rather not call the body of my
interrupt handler as a subroutine for the special case of my first
transmission.  Any ideas?

Thanks,

Jeff
