I/O PORTS (Cont’d)
4.1.2 I/O Pin Programming
Each pin can be individually programmed as input
or output with different input and output configura-
tions. This is achieved by writing to the relevant bit
in the data (DR) and data direction register (DDR).
Table 10 shows all the port configurations that can
be selected by the user software.
4.1.3 Input/Output Configurations
The Table 9 shows the I/O lines hardware configu-
ration for the different options.
Notes: The WAIT instruction allows the ST638x to
be used in situations where low power consump-
tion is needed. This can only be achieved however
if the I/O pins either are programmed as inputs
with well defined logic levels or have no power
consuming resistive loads in output mode. As the
same die is used for the different ST638x versions
the unavailable I/O lines of ST638x should be pro-
grammed in output mode.
Single-bit operations on I/O registers are possible
but care is necessary because reading in input
mode is made from I/O pins while writing will di-
rectly affect the Port data register causing an un-
desired changes of the input configuration.

Note: X. Means don’t care.
4.1.4 I/O Port Registers
4.1.4.1 Data Registers
Ports A, B, C Data Register
Address: C0h (PA), C1h (PB), C2h (PC) - Read/
Write
Reset Value: 00h
PA7-PA0. These are the I/O port A data bits. Re-
set at power-on.
PB7-PB0. These are the I/O port B data bits. Re-
set at power-on.
PC7-PC0. Set to 04h at power-on. Bit 2 (PC2 pin)
is set to one (open drain therefore high imped-
ance).
4.1.4.2 Data Direction Registers
Port A, B, C Data Direction Register
Address: C4h (PA), C5h (PB), C6h (PC) - Read/
Write
Reset value:00h
PA7-PA0. These are the I/O port A data direction
bits. When a bit is cleared to zero the related I/O
line is in input mode, if bit is set to one the related
I/O line is in output mode. Reset at power-on.
PB7-PB0. These are the I/O port B data direction
bits. When a bit is cleared to zero the related I/O
line is in input mode, if bit is set to one the related
I/O line is in output mode. Reset at power-on.
PC7-PC0. These are the I/O port C data direction
bits. When a bit is cleared to zero the related I/O
line is in input mode, if bit is set to one the related
I/O line is in output mode. Set to 04h at power-on.
Bit 2 (PC2 pin) is set to one (output mode select-
ed).
