Abstract
A data acquisition method of acquiring and latching data with a timing based on an input signal supplied to an input port, the method including: acquiring and retaining the data with a timing of when an edge of the input signal is detected, and starting a timer; and at the time of expiration of the timer, if the level of the input signal is a first level that is unchanged from start of the timer, latching the retained data and if the level of the input signal is a second level that is changed from the start of the timer, discarding the retained data.
Claims7
A data acquisition method of acquiring and latching data with a timing based on an input signal supplied to an interrupt input port, the method comprising:
- acquiring through an input port different from the interrupt input port and retaining the data at a timing at which an edge of the input signal is detected, and starting a timer;
- and
- at an expiration time of the timer, if the level of the input signal is a first level that is unchanged from start of the timer, latching the retained data and if the level of the input signal is a second level that is changed from the start of the timer, discarding the retained data.
A data acquisition apparatus that acquires and latches data with a timing based on an input signal supplied to an interrupt input port, wherein
- the data is acquired through an input port which is different from the interrupt input port and retained at an edge of the input signal being detected, and a timer is started;
- and
- at an expiration time of the timer, if the level of the input signal is a first level that is unchanged from start of the timer, the retained data is latched and if the level of the input signal is a second level that is changed from the start of the timer, the retained data is discarded.
