PURPOSE:To attain simultaneously the transmission and reception of a data by providing two timers to apply unique interruption processing control. CONSTITUTION:The timers 5, 6 have respectively an independent interruption signal generating function to generate the timing for data transmission/reception. Moreover, an interruption transmission processing means transmits a serial data according to an interruption signal INT2 generated by the timer 6. Then the interruption reception processing means has a higher priority than that of the interruption transmission processing means and receives the serial data according to the generated interruption signal INT1. Thus, the reception operation during the transmission operation and the transmission operation during the reception are performed simultaneously. |
