I/O beans

The BitsIO bean encapsulate group of 1-8 adjacent bits of a CPU input/output port.

The BitsIO bean encapsulate a one-byte input/output. It uses one 8-bit port.

This bean implements a two-byte input/output. It is an encapsulation of a 16-bit input/output that uses any two 8-bit ports.

This bean implements a word input/output. It uses one 16-bit port (port with 16-bit access; i.e. one can write/read a 16-bit value using one instruction).

This bean implements a three-byte input/output. It uses any three 8-bit ports.

This bean implements a four-byte input/output. It uses any three 8-bit ports.

This bean implements a long word (32-bit) input/output. It uses one 32-bit port (port with 32-bit access; i.e. one can write/read a 32-bit value using one instruction).

This bean implements an external byte input/output. It requires additional hardware - an external 8-bit port connected to the processor using address and data busses.

This bean implements an external word input/output. It requires additional hardware - an external 16-bit port connected to the processor using address and data busses.

This bean implements an external long-word input/output. It requires additional hardware - an external 32-bit port connected to the processor using address and data busses.

This bean implements an external one-bit input/output. It uses one bit/pin of a port.

This bean implements an external multi bit input/output.

This bean implements an external one-byte input/output. It uses one 8-bit port.

The bean catches an external interrupt. The interrupt is caused by a signal level/edge on a pin.

The watchdog timer counts until it reaches a critical value corresponding to the period specified. Then, the watchdog causes a CPU reset or a NMI (non-maskable interrupt) that you can handle by a subroutine (see OnWatchDog event).
