14. High Voltage I/O Ports
14.1
8042B–AVR–06/10
Overview
All high voltage AVR ports have true Read-Modify-Write functionality when used as general dig-
ital I/O ports. This means that the state of one port pin can be changed without unintentionally
changing the state of any other pin with the SBI and CBI instructions. All high voltage I/O pins
have protection Zener diodes to Ground as indicated in
tics” on page 230
Figure 14-1. High Voltage I/O Pin Equivalent Schematic
All registers and bit references in this section are written in general form. A lower case “x” repre-
sents the numbering letter for the port, and a lower case “n” represents the bit number. However,
when using the register or bit defines in a program, the precise form must be used. For example,
PORTC3 for bit number three in Port C, here documented generally as PORTxn. The physical
I/O Registers and bit locations are listed in
One I/O Memory address location is allocated for each high voltage port, the Data Register –
PORTx. The Data Register is read/write.
Using the I/O port as General Digital Output is described in
