Timer
The timer of the W56xxx is a quite simple mechanism to facilitate applications with timed
events. Once the timer interrupt is enabled, the timer starts to down-count as long as the "LD
timer, operand" is executed. Upon reaching the overflow condition, the timer interrupt occurs and
the timer_interrupt subroutine is serviced.
Users have to re-load the timer with a new value in order to start the timer again, since there's no
auto-reload function in it.
Interrupt Control
During the period of a specific ISR, other interrupts except for POR & synth are disabled by H/W
automatically. Users may enable certain interrupts under S/W control: "LD IER, operand", or "EN
INT".
Under normal conditions, the disabled interrupt situation disappears automatically when RTI of
that specific ISR is encountered. Figure 0-5 shows the arbitrator of all the interrupt sources.
