Note 1: In normal operation this switch should be left OFF. However, if running a
transparent asynchronous application (TD, RD and no clock) enable this switch. This
will disable the automatic clock polarity function and allow error free transparent
operation. (Added in firmware version V1.2 and CPLD version V1.4)
