PLL Interrupt Control
The PLL unit is able to generate a service request output signal PLLSR. This signal is
controlled as shown in Figure 24-19. When the service request condition PLLCNT = 0
occurs, the service request flag is always set. The service request output PLLSR is
activated only if it is enabled by the enable bit PLLCTR.REN. Additional information
about service request and interrupt handling are given in section “Interrupt Sharing
Unit (IS)” on Page 24-112.
