(2) Port Direction Registers
When a pin is functioning as a port, the corresponding pin control setting is as follows :
0 : Input mode
1 : Output mode The register value is “0” at reset.
Port 76, 77
These ports do not have DDR registers. Data at these pins is always valid, so that when P76, P77 are used
as I
2
C pins the PDR value should be “1”. (The I
2
C functions should be stopped, when these pins are used as
P76,P77 .)
These ports have open drain configuration. If they are used as input ports, the output transistor is turned off,
so that the output data register must be set to “1” and pull-up resistance applied.
Note : If these registers are accessed using read-modify-write instructions (such as bit set instructions) ,the bit that
is the object of the instruction will be set to the specified value but for other bits the value of the corresponding
output register will be rewritten to the input value of the pin at that time. For this reason when a pin used for
input is switched to output, first write the desired value to the PDR register, then set the DDR register to
switch the pin direction.
