Connected to the first 4 data lines of the LCD module, the i.MX23 IC
will read the voltage levels on these pins when the i.MX23 IC is
initially powered on to determine what mode the IC should boot into.
Table 2.2 lists the various Boot Mode options.

Optional Button connected to the CPLD which will force the CPLD to
reset and resume operations. This button can be populated when
software JTAG reset functionality is not present or insufficient for
the users need.
20-Pin standard JTAG connector connects to on board CPLD pre-
programmed to convert parallel JATG data into a proprietary
serialized data stream. Reset commands are separated from the
stream and formatted to correctly stop and restart the i.MX23 IC.
USB connector conforms to new USB standard micro connector
requirements. The AB format allows using the EVK as a USB Host
when additional components are populated. D+ and D- traces are
connected directly to the I.MX23 IC. The USB_5V power rail goes
through a switch to allow for manual removal of 5V power to the IC.
Standard RJ45 Jack connects to a SPI Ethernet IC through an
isolation transformer. Ethernet IC communicates with i.MX23 via the
SPI port also used by the SD/MMC card. A buffer IC disconnects
the Ethernet IC from the CPU when an SD/MMC card is inserted
and reconnects the Ethernet hardware when the SD/MMC card is
removed.
5.0V DC power connector. Provides power to a linear regulator
which outputs simulated 4.2V battery power for use by the i.MX23
CPU. The external 5V rail also supplies power to two Linear
Regulators which independently supply power to the CPLD,
Ethernet IC, and UART line drivers. When the EVK is used in USB
Host mode, 5V power is also supplied directly from the 5.0V DC
Power Supply.
Directly connected to the two External Speaker pins of the i.MX23
IC, these pins can drive an attached external speakers, typically 4
Ohms.
