from 0x0000 to 0x03FF, which indicates the voltage
relative to Vdd.
Example:
96
Command – Get Analog
96 02 36
Response – V = Vdd * (0x236/0x3FF)
Set Pin
The identifier SETPIN (0x91) sets the value of any
output pin. The command payload has two bytes, which
indicate the pin and the desired output.
Example:
91 25 01
Command – Set DTR pin active

*Byte 0 is the identifier 0x90 (Get Pin) or 0x91 (Set Pin)
** Used in Get Pin Response and Set Pin Command only
Host Ready
The Host Ready feature is used to indicate to the device
that a host application is running, has located the device,
and is ready to communicate with it.
If the Host Ready pin is implemented, the application
should tell the device when it is ready using the Host
Ready command.
It consists of the identifier
HOSTREADY (0x92) and one payload byte, which is
0x01 if the application is initialized and available, or
0x00 if the application is shutting down and not longer
available.
Interrupt
The Interrupt response is an unprompted message from
the device that an interrupt input transitioned from the
inactive to the active state.
It consists of the identifier INTERRUPT (0x95) and one
payload byte, which is 0x09 if the interrupt occurred on
pin VIO9, or 0x0A if the interrupt occurred on pin VIO10.
Set Serial
The identifier SETSERIAL (0x93) temporarily sets the
baud, parity and flow control characteristics of the
device. These settings are not remembered after device
reset and should be used if the settings are to be
frequently adjusted under software control.
The
command payload has three bytes as shown in table 7.
Example:
93 06 02 A0
Command – Set serial 9600, hardware
flow control, 8 bits, odd parity, no ack

0x10 for ack on send to host

BitFields
Data, parity and stop bits (excl start
and final stop bits):
OR
0x00 for 8 bits including any
parity and stop bits
0x80 for 9 bits including any
parity and stop bits
WITH 0x05 if 8th bit is data
0x01 if 8th bit is stop bit
0x02 if 8th bit is odd parity
0x03 if 8th bit is even parity
0x04 if 8th bit is mark parity
0x01 if 8th bit is space parity
WITH 0x10 if 9th bit is stop bit
0x20 if 9th bit is odd parity
0x30 if 9th bit is even parity
0x40 if 9th bit is mark parity
0x10 if 9th bit is space parity
Note: prior to revision 7, the parity bit was not stripped
from incoming 7-bit-with-parity data.
To maintain
compatibility with revisions earlier than rev 7, the bit
should be stripped off in PC software.
Get Firmware ID
The identifier GETFWID (0x94) retrieves a zero-
terminated ASCII text string identifying the firmware and
its version number.
Example:
94
Command – Get Firmware ID
94 55 53 42 2D 32 33 32 20 30 30 30 35 00
