  • Page 103 K1M0 • A word device D (data register), T (current value of a timer), or C (current value of a counter) consists of 16 bits (one word), and data is basically transferred in one device. • With 16 bit devices (such as X, Y, and M), data of the same size as a word device can be handled. The device numbers allocated to the bit devices must be in consecutive order.
