35.3.16 DMM Pin Control 0 (DMMPC0)

This register defines if the DMM pins are used in functional or GIO mode. It should only be written when

ON/OFF = 0101 and the BUSY bit = 0 (Section 35.3.1). If pins other than the pins specified in Table 35-5

are configured, or DMMCLK and DMMSYNC are programmed as non-functional pins, no operation in

trace mode or direct data mode is possible.
