This bean implements a word input/output. It uses one 16-bit port (port with a 16-bit access; i.e., a 16-bit value can be written/read using one instruction). If there is no such 16-bit port available, it is possible to use the Byte2IO bean instead (although it is less efficient implementation since it requires two instructions for accessing two 8-bit ports instead).

This bean belongs to the category: CPU Internal Peripherals-Port I/O
