AT43USB355
2603G–USB–04/06
Port F
In the AT43USB355 Port F[1:3] is a 3-bit bi-directional I/O. Its output buffers can sink or source
2 mA Three I/O memory address locations are allocated for the Port F, one each for the Data
Register (PORTF), $06($26), Data Direction Register (DDRF), $05($25) and the Port F Input
Pins (PIND), $04($24). The Port F Input Pins address is read only, while the Data Register
and the Data Direction Register are read/write.
PF1 to PF3 pins have individually selectable pull-up resistors. When pins PPF1 to PF3 are
used as inputs and are externally pulled low, they will source current if the internal pull-up
resistors are activated.
In the SRAM version of the chip, the AT43USB355E, Port F is used for program memory
downloading immediately after power-on reset. After downloading is completed, PF0 is driven
high, while PF[1:3] becomes available as GPIO. In both versions of the chip, PF3 can be pro-
grammed as ICP, Timer/Counter 1 Input Capture.
Port F Data Register – PORTF
Port F Data Direction Register – DDRF
Port F Input Pins Address – PINF
The Port F Input Pins address (PINF) is not a register, and this address enables access to the
physical value on each Port F pin. When reading PORTF, the Port F Data Latch is read, and
when reading PINF, the logical values present on the pins are read.
