4-3. X-Y-Z Measurement Mode
When PM12AD bit is “1” and then ADMODE1-0 bits are set to “10”, the AK4650 measures X-position as many times as
set by MSR1-0 bits at first, Y-position as many times as set by MSR1-0 bits at second, the item set by A2-0 and SER bits
for times set by MSR1-0 bits at third. Measurement results are output via slot after wait time set by DLY3-0 bits.
(1)
When SLOT bit = “1”, pen touch waiting state (PM12AD bit = “1” and PINTE bit = “1”) should be set.
(2)
When the controller receives PEN Interrupt, the controller should set PM12AD bit = “1” so that 12bit ADC is
powered-up. ADMODE1-0 bits should be set to “10” at the same time. Then data is output via slot.
(3)
After the wait time set by DLY3-0 bits, the AK4650 measures X-position as many times asset by MSR1-0 bits and
outputs the result via slot.
(4)
After X-position measurement and the wait time set by DLY3-0 bits, the AK4650 measures Y-position as many times
as set by MSR1-0 bits and outputs the result via slot.
(5)
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 as many times as set by MSR1-0 bits and outputs the result via slot.
(6)
After the measurement, 12bit ADC is powered-down and the AK4650 waits for pen touch.
5. ADEXE pin
When the AK4650 measures the position during the data is sent to LCD, the position measurement result may have some
error caused by the noise from LCD. The AK4650 prepares the measurement mode by using sync signal from LCD after
data transferring is completed. The sync signal is input to ADEXE pin of the AK4650.

Method using Slot 12 of SDATAIN
When SLOT bit is “1”, pen interrupt and headphone jack detection results are output via slot 12 of SDATAIN.
Bit 1: Headphone jack detection result
Bit 0: Pen interrupt
