The I/O connector features 32 general-purpose 3.3 V CMOS I/O pins that can be used as
outputs or inputs interfacing to external logic. All I/Os are 5 V tolerant. Some of the gen-
eral-purpose I/O pins support dual mode functions (SPI, Timer I/O, UARTs, and bit I/O
with edge- or level-triggered interrupt functions on each pin). For more information on

(PS0192).
An onboard Panasonic VL-1220-1VC 3 V Lithium battery powers the 32 kHz
real-time clock when external power is removed. The battery is charged through diode
CR1 and resistor R28 when external power is applied to the board.
The Zdots
(MII) and a HALO RJ45 with integrated magnetics (transformer and common-mode
chokes) and two LED indicators.
The MII enables different modes of Ethernet communication, configurable by resistors
R19, R21, R23, and R24. The Zdots is shipped with all four resistors installed.
