Port E Pin Control Registers (PTEPE, PTESE, PTEDS)
Data Direction for Port E Bits — These read/write bits control the direction of port E pins and what is read for
PTED reads.
0 Input (output driver disabled) and reads return the pin value.
1 Output driver enabled for port E bit n and PTED reads return the contents of PTEDn.
Internal Pullup Enable for Port E Bits— Each of these control bits determines if the internal pullup device is
enabled for the associated PTE pin. For port E pins that are configured as outputs, these bits have no effect and
the internal pullup devices are disabled.
0 Internal pullup device disabled for port E bit n.
1 Internal pullup device enabled for port E bit n.
