10.16.2 Port H Data Register (PHDR)
PHDR stores output data for the port H pins.
Bit Bit Name Initial Value R/W Description
7
to
4
⎯ All 0 ⎯ Reserved
These bits are reserved; they are always read as 0
and cannot be modified.
3 PH3DR 0 R/W
2 PH2DR 0 R/W
1 PH1DR 0 R/W
Output data for a pin is stored when the pin function
is specified to a general purpose I/O.
0 PH0DR 0 R/W
10.16.3 Port H Register (PORTH)
PORTH shows port H pin states.
PORTH cannot be modified.
Bit Bit Name Initial Value R/W Description
7
to
4
⎯ Undefined ⎯ Reserved
If these bits are read, they will return an undefined
value.
3 PH3 ⎯* R
2 PH2 ⎯* R
1 PH1 ⎯* R
0 PH0 ⎯* R
If a port H read is performed while PHDDR bits are
set to 1, the PHDR values are read. If a port H read
is performed while PHDDR bits are cleared to 0, the
pin states are read.
Note: * Determined by the states of pins PH3 to PH0.
