Manufacturer Part Number
upd78f0114m6gb-8es
Description
8-bit Single-chip Microcontrollers
Manufacturer
Renesas Electronics Corporation.
Datasheet
(2) Port registers (P0 to P3, P6, P7, P12, and P13)
Symbol
P12
P13
These registers write the data that is output from the chip when data is output from a port.
If the data is read in the input mode, the pin level is read. If it is read in the output mode, the value of the output
latch is read.
These registers can be set by a 1-bit or 8-bit memory manipulation instruction.
RESET input clears these registers to 00H (but P2 is undefined).
