3-3. XYZ Measurement Mode
When ADMODE1-0 bits are set to “10” and PM12AD bit is “1”, the AK4650 measures X-position at first, Y-position at
second, the item set by A2-0 and SER bits at third, and reports X-position to 74H, Y-position to 76H, third result to 78H,
respectively. 74H, 76H and 78H registers are cleared by PM12AD bit = “0”.
(1)
70H(ADFLT, DLY3-0, MSR1-0, ADEXE1-0) is set. Measurement mode should be set by A2-0 and SER bits, and
ADMODE1-0 bits should be set to “10” at the same time. 12bit ADC is powered-up by setting PM12AD bit = “1”.
(2)
After the wait time set by DLY3-0 bits, the AK4650 measures X-position and reports the result to 74H. When
ADFLT bit is “1”, averaged data of four measurement results is reported to 74H.
(3)
After X-position measurement and the wait time set by DLY3-0 bits, the AK4650 measures Y-position and reports
the result to 76H. When ADFLT bit is “1”, averaged data of four measurement results is reported to 76H.
(4)
After Y-position measurement and the wait time set by DLY3-0 bits, the AK4650 measures the item set by A2-0 and
SER bits, and reports the result to 78H. When ADFLT bit is “1”, averaged data of four measurement results is
reported to 78H.
(5)
After the measurement, ADMODE1-0 bits are automatically reset to “00”.
(6)
When PINTE bit = “1”, 12bit ADC is powered-down and the AK4650 waits for pen touch.

When ADMODE1-0 bit is set to “10” again, then the AK4650 set ADE bit as “0” and measurement is executed again.
