Sequence based on round-robin.
GPIO access mode selection.
GPIO ports 0 and 1 are accessed via APB addresses in a fashion
compatible with previous LPC2000 devices.
High speed GPIO is enabled on ports 0 and 1, accessed via addresses in
the on-chip memory range. This mode includes the port masking feature
described in the GPIO chapter.
External Memory Controller Reset Disable.
Both EMC resets are asserted when any type of reset event occurs. In this
mode, all registers and functions of the EMC are initialized upon any reset
condition.
Many portions of the EMC are only reset by a power-on or brown-out event,
in order to allow the EMC to retain its state through a warm reset (external
reset or watchdog reset). If the EMC is configured correctly, auto-refresh can
be maintained through a warm reset.
External Memory Controller burst control (implemented on device revisions
C and higher).
Burst enabled.
Burst disabled.
MCIPWR pin control.
The MCIPWR pin is low.
The MCIPWR pin is high.
Main oscillator range select.
The frequency range of the main oscillator is 1 MHz to 20 MHz.
The frequency range of the main oscillator is 15 MHz to 25 MHz.
