PS1, Line 98:  * TCK/SK is bit 0.
            :  * TDI/DO is bit 1.
            :  * TDO/DI is bit 2.
            :  * TMS/CS is bit 3.
            :  * GPIOL0 is bit 4.
            :  * GPIOL1 is bit 5.
            :  * GPIOL2 is bit 6.
            :  * GPIOL3 is bit 7.
Shouldn't this be code, e.g. macros or an enum?
