  • Patent number: 5481252
    Abstract: A mode conversion method for performing an input/output of the control data in a multifunctional programmable remote controller having multi-band remote function and learning functions, including the steps of checking for which key is selected among a mode key, a set key, and normal keys, converting to a waiting mode when the setting is not in progress if a key signal is not input, and displaying the selected mode within a certain time and converting to a using mode when the setting is in progress, then, inspecting the setting condition if the mode key is selected so that if the setting is not in progress, each mode display is toggled to indicate that the mode is converted, and if the setting is in progress, the current step returns to a key scanning step for determining whether the current mode is a using mode or a setting mode so that if it is the using mode, data is output and displayed by modes and if it is the setting mode, the mode is selected.

  • Patent number: 5264845
    Abstract: A key scan circuit and the method thereof in a microcomputer is disclosed which requires no diode for preventing circuit short and performs key check or automatic operations with a simplified circuit structure. The key scan method includes a step of designating the input/output mode of a bilateral port by a data direction register in a microcomputer which includes an input/output bilateral port and an input only unilateral port, so as to prevent circuit shorts when more than one key are pushed. Further, by using first and second memories, the key scan method includes a step of determining whether the number of logic low states in the first memory is greater than one, and determining whether the number of logic high states stored in the second memory is greater than one, thus indicating the pressing of multiple keys.
