it is a negative edge, HI8. From that point, an edge-detect status bits (CTR1 D1,
D0) is set, and an interrupt can be generated if enabled (CTR0 D2). Meanwhile,
T8 is loaded with FFh and starts counting again. If T8 reaches 0, the time-out sta-
tus bit (CTR0 D5) is set, an interrupt can be generated if enabled (CTR0 D1), and
T8 continues counting from FFh (see Figure 36 and Figure 37).
