These 24 I/O lines comprise ports A, B and C. The state of any pin is software programmable, and
all the pins are configured as inputs during power-on or reset.
Under software control the PC2 pin can output the internal E-clock (see
2.5.18
This 8-bit input only port (D) shares its pins with the A/D converter. When enabled, the A/D
converter uses pins PD0/AN0 – PD7/AN7 as its analog inputs. On reset, the A/D converter is
disabled which forces the port D pins to be input only port pins (see
