CHAPTER 15 OPTION BYTE.
P32 is a 1-bit I/O port. In addition to the function as an I/O port pin, this pin also has a function to input an external
P34 is a 1-bit input-only port. This pin is also used as a RESET pin, and when the power is turned on, this is the
For the setting method for pin functions, see CHAPTER 15 OPTION BYTE.
When P34 in PD78F920x is used as an input port pin, connect the pull-up resistor.
P32 and P34 can be set to the following operation modes in 1-bit units.
(1) Port mode
(2) Control mode
Caution In PD78F950x, the P34/RESET pin is pulled up during reset by the reset pin function/power-on
P40 and P43 constitute a 2-bit I/O port. Each bit of this port can be set to the input or output mode by using port
Note
This pin inputs an active-low system reset signal.
Caution In PD78F950x, the P34/RESET pin is pulled up during reset by the reset pin function/power-on
These pins connect an oscillator to oscillate the X1 input clock.
X1 and X2 also function as P23/ANI3 and P22/ANI2, respectively. For the setting method for pin functions, see
Supply an external clock to X1.
Caution The P22/X2/ANI2 and P23/X1/ANI3 pins are pulled down during reset.
P32 functions as a 1-bit I/O port. This pin can be set to the input or output mode by using port mode register 3
(PM3). In addition, an on-chip pull-up resistor can be connected to the port by using pull-up resistor option
register 3 (PU3).
P34 functions as a 1-bit input-only port. In PD78F950x, an on-chip pull-up resistor can be connected to the
port by using pull-up resistor option register 3 (PU3).
P32 functions as an external interrupt request input pin (INTP1) for which the valid edge (rising edge, falling
edge, or both rising and falling edges) can be specified.
In PD78F920x, set PM41, PM42, and PM44 to PM47 to "0" at program initialization.
