KEY CODES
Key codes range from 01H to 73H
and are arranged as follows:
Make code = column_number * 8 +
row_number + 1
Break code = Make code OR 80H
Discrete Switches transmit the
following codes:
XSW = 71H
SW0 = 72H

Figure 3: The behavior of an LED using the settings 1: LED on; 0: LED off.
The UR5HCSPI provides three LED pins. There are three LED modes: off,
on, and blinking. The LED can be individually set to one of these modes. In
the Blinking Mode, both the on-interval and the off-interval can be
individually set. Additionally, a meta blink count and meta blink interval
may be specified. This describes an interval of a different length which may
be inserted after each specified number of blinks. All the intervals are
based on a 1/16th of a second duration. When the LED is on or blinking, the
SPICoderTM will not enter the STOP Mode unless the PWR_OK signal is
asserted low. In this case, the device will save the status of the LED and
turn it off. The default LED mode is off.
The above timing chart describes the behavior of an LED using these
settings,1: LED on; 0: LED off.
