5.5 ISE A/D Conversion
(1) ISE A/D Conversion Timing
(a) As shown in the above figure, measure the electromotive force 5 times each for Na,
K and Cl in this order.
(b) The A/D conversion interval time for each is 10 msec.
(c) ADC alarm is issued if the ADC count, even once, is 0.
(2) ADC Setting Parameters
• Number of integrations : 8
• Software trigger interval : 10 msec
(3) ISE ADC Calibration Timing
(a) As shown in the above figure, measure the reference voltages
(2 V, 8 V and offset voltage).
(b) The A/D conversion interval time for each is 10 msec.
(c) At the time of initialization and T/M resetting, the RESET command is issued for the
ADC controller.
(d) Number of integrations (1 time) = 8
