6.17.3 Reset and wake-up timer
Reset has two sources on the LPC2101/02/03: the RST pin and watchdog reset. The RST
pin is a Schmitt trigger input pin with an additional glitch lter. Assertion of chip reset by
any source starts the wake-up timer (see wake-up timer description below), causing the
internal chip reset to remain asserted until the external reset is de-asserted, the oscillator
is running, a xed number of clocks have passed, and the on-chip ash controller has
completed its initialization.
When the internal reset is removed, the processor begins executing at address 0, which is
the reset vector. At that point, all of the processor and peripheral registers have been
initialized to predetermined reset values.
The wake-up timer ensures that the oscillator and other analog functions required for chip
operation are fully functional before the processor is allowed to execute instructions. This
is important at power on, all types of reset, and whenever any of the aforementioned
functions are turned off for any reason. Since the oscillator and other functions are turned
off during Power-down and Deep power-down mode, any wake-up of the processor from
the Power-down modes makes use of the wake-up timer.
The wake-up timer monitors the crystal oscillator as the means of checking whether it is
safe to begin code execution. When power is applied to the chip, or some event caused
the chip to exit Power-down mode, some time is required for the oscillator to produce a
signal of sufcient amplitude to drive the clock logic. The amount of time depends on
many factors, including the rate of VDD ramp (in the case of power on), the type of crystal
and its electrical characteristics (if a quartz crystal is used), as well as any other external
circuitry (e.g., capacitors), and the characteristics of the oscillator itself under the existing
ambient conditions.
