External Clock Input—An external clock source must be connected to EXTAL in
order to supply the clock to the internal clock generator and PLL.
PLL Capacitor—PCAP is an input connecting an off-chip capacitor to the PLL filter.
Connect one capacitor terminal to PCAP and the other terminal to V
If the PLL is not used, PCAP may be tied to V
PLL Initial/Nonmaskable Interrupt—During assertion of RESET, the value of
PINIT/NMI is written into the PLL Enable (PEN) bit of the PLL control register,
determining whether the PLL is enabled or disabled. After RESET de assertion and
during normal instruction processing, the PINIT/NMI Schmitt-trigger input is a
negative-edge-triggered nonmaskable interrupt (NMI) request internally
synchronized to internal system clock.
This input is 5 V tolerant.
