The above chart shows the 8 wash progress LEDs with the SPIN LED corresponding to the leftmost.
8 bit binary calculations: LSB is the SPIN LED. If it is on this has a value of 1. The MSB is the first wash
LED, this has a value of 128 if it is on. The intermediate LEDs have values of 64, 32, 16, 8,4 and 2. By
adding up the value of all the LEDs that are illuminated the 8 bit binary value may be calculated. NB. If
Spin LED is optically downloading it will be 'flickering', this does not necessarily count as part of the
8 bit value.
To calculate a 16 bit value (e.g. number of cycles) TOTAL = (high byte x256) + (low byte).
