McASP Registers
22.4.1.7 Pin Data Set Register (PDSET)
The pin data set register (PDSET) is an alias of the pin data output register (PDOUT) for writes only.
Writing a 1 to the PDSET bit sets the corresponding bit in PDOUT and, if PFUNC = 1 (GPIO function) and
PDIR = 1 (output), drives a logic high on the pin. PDSET is useful for a multitasking system because it
allows you to set to a logic high only the desired pin(s) within a system without affecting other I/O pins
controlled by the same McASP. The PDSET is shown in
and described in
CAUTION
Writing to Reserved Bits
Writing a value other than 0 to reserved bits in this register may cause improper
device operation.
