SD24_B converter-2 bit stream data input/output (direction controlled by SD24_B)
Disables the output driver as well as the input Schmitt-trigger to prevent parasitic cross
currents when applying analog signals.
31(0FFh)(1)
PM_ANALOG
(1) The value of the PM_ANALOG mnemonic is set to 0FFh. The port mapping registers are only 5 bits wide and the upper bits are ignored
resulting in a read out value of 31.
