LPC2212/2214
Single-chip 16/32-bit ARM microcontrollers
[1]
SSP interface available on LPC2212/01 and LPC2214/01 only.
6.6 Pin connect block
The pin connect block allows selected pins of the microcontroller to have more than one
function. Configuration registers control the multiplexers to allow connection between the
pin and the on chip peripherals. Peripherals should be connected to the appropriate pins
prior to being activated, and prior to any related interrupt(s) being enabled. Activity of any
enabled peripheral function that is not mapped to a related pin should be considered
undefined.
6.7 External memory controller
The external Static Memory Controller (SMC) is a module which provides an interface
between the system bus and external (off-chip) memory devices. It provides support for
up to four independently configurable memory banks (16 MB each with byte lane enable
control) simultaneously. Each memory bank is capable of supporting SRAM, ROM, flash
EPROM, burst ROM memory, or some external I/O devices.
Each memory bank may be 8-bit, 16-bit, or 32-bit wide.
6.8 General purpose parallel I/O (GPIO) and Fast I/O
Device pins that are not connected to a specific peripheral function are controlled by the
parallel I/O registers. Pins may be dynamically configured as inputs or outputs. Separate
registers allow setting or clearing any number of outputs simultaneously. The value of the
output register may be read back, as well as the current state of the port pins.
6.8.1
Features
Bit-level set and clear registers allow a single instruction set or clear of any number of
bits in one port.
Direction control of individual bits.
Separate control of output set and clear.
All I/O default to inputs after reset.
6.8.2
Features added with the Fast GPIO set of registers available on
LPC2212/2214/01 only
Fast GPIO registers are relocated to the ARM local bus for the fastest possible I/O
timing, enabling port pin toggling up to 3.5 times faster than earlier LPC2000 devices.
Mask registers allow treating sets of port bits as a group, leaving other bits
unchanged.
All Fast GPIO registers are byte addressable.
Entire port value can be written in one instruction.
Ports are accessible via either the legacy group of registers (GPIOs) or the group of
registers providing accelerated port access (Fast GPIOs).
