eXtended Commands (requires V2.00+)

The eXtended commands are used to generate “out-of-spec” signaling. eXtended
commands cannot use the I2C hardware to control the SCL and SDA lines, as the
I2C hardware only generates I2C compatible signals. The eXtended commands use
firmware to “bit-bang” the SCL and SDA lines. This firmware cannot operate as fast
as the hardware, and it can be interrupted at any time by internal interrupts. The
eXtended commands run directly off the command characters as they are received
on the RS-232 link. Speed of execution of eXtended commands is controlled by the
RS-232 baud rate, the execution speed of the firmware, delays caused by execution
interruptions that may occur while a command is executing, and I2C Bus clock-
stretching by external slave devices.

The following commands manipulate the I

2

C Clock (SCL) and data (SDA) lines.
