/*************************************************************
*       jl16-0.c - Demonstrate simple I/O functions of MC68HC908JL16
*
*       Program loops turning PTA0 on and off as fast as possible.
*
* The program should generate code in the loop consisting of
*   LOOP:   BSET 0,PTA          (4 cycles)
*           BCLR 0,PTA          (4 cycles)
*           BRA  LOOP           (3 cycles)
*
* PTA0 will be low for 7 * 4 / OSC1 freq
* PTA0 will be high for 4 * 4 / OSC1 freq
* A 9.8304MHz clock gives a loop period of about 4.5 microseconds.
