I
C (Inter-Integrated Circuit) is a multi-master serial computer bus invented by Philips
that is used to attach low-speed peripherals to a motherboard, embedded system, or
cellphone. The name is pronounced eye-squared-see or eye-two-see.

I
C uses only two bidirectional open-drain lines, Serial Data (SDA) and Serial Clock
(SCL), pulled up with resistors. Typical voltages used are +5 V or +3.3 V although
systems with other, higher or lower, voltages are permitted.

The I
C reference design has a 7-bit address space with 16 reserved addresses, so
a maximum of 112 nodes can communicate on the same bus.
COM port connector (CN39, CN40, CN41, CN42 and CN43)
COM is the original, yet still common, name of the serial port interface on IBM PC-
compatible computers.PCM-9562 can support 4 RS-232 ports (CN39, CN40, CN41,
CN43) and 2 RS-422/485 (CN42). COM6 (CN43) is photo isolated and complies with
UL60601.
-5 V and -12 V Connector (CN44)
CN44 is a wafer type 3-pin connector for -5 V and -12 V.
SPI Flash socket (CN45)
CN45 is a socket for BIOS flash. PCM-9562 uses a 16Mbit capacity flash for BIOS.
SATA Power Connecter (CN46)
CN46 is SATA Power Connecter
