NOTES:
1. When TZS bit=1 (starts counting), the value set in the TZWC bit is valid. If TZWC bit=0, the timer Z count value is
written to both reload register and counter. If TZWC bit=1, the timer Z count value is written to the reload register
only.
When TZS bit=0 (stops counting), the timer Z count value is written to both reload register and counter regardless of
how the TZWC bit is set.
