2.1. Connecting the Power Supply
The MK-200 requires a +5 V operating voltage. An embedded regulator is
used to supply the internal +3.3 V digital power. The +5 V pins must be
connected to a +5 V power supply with external decoupling capacitors
(one 100 nF ceramic capacitor for each +5 V) as shown Figure 4. The
decoupling capacitors shall be placed close to the +5V pins whenever
possible for best performance.

2.2. Connecting the Host
A host is required to drive the MK-200 through the UART interface with the
following configurations:
Baud rate: 115200 bps
Data bit: 8
Stop bit: 1
Parity bit: None
Flow control: None
These configurations are not changeable.
The UART interface can be connected directly to another host processor
with a UART port (See Figure 5). If the MK-200 is to be connected to a
