13.2 - Multiplexage of two blocks of 16 Analog Inputs
The ADC can manage 16 analog inputs, so to increase its capability, a new XADCMUX register is added
to control the multiplexage between the first block of 16 channels on Port5 and the second block of 16
channels on XPort10. The conversion result register stays identical and only a software management can
determine the block in use.
Figure 52 : Block Diagram
The XADCMUX register is enabled by setting XPEN bit 2 of the SYSCON register and bit 3 of the new
XPERCON register
