Reset
The 87LPC769 has an active low reset input when configured for an
external reset. A fully internal reset may also be configured which
provides a reset when power is initially applied to the device. The
watchdog timer can act as an oscillator fail detect because it uses
an independent, fully on-chip oscillator.
The external reset input is disabled, and fully internal reset
generation enabled, by programming the RPD bit in the EPROM
configuration register UCFG1 to 0. EPROM configuration is
described in the section EPROM Characteristics
