4. Method using SDATAIN Slot
When SLOT bit is “1”, 12bit ADC data is output via slot 5, 6 or 12 of SDATAIN. When SLOTNO1-0 bits are “00”, “01”
or “10”, slot 5, 6 or 12 is used, respectively. Output data is 16bit. The measurement result is output only when 12bit ADC
is executed. When data is output, tag bit for slot 5, 6 or 12 (bit 10, 9 or 3) is set to “1”. When ADC is not executed, tag bit
is set to “0” and data of slot 5, 6 or 12 are set to all “0”.

Table 50. Slot number setting for 12bit ADC measurement result output
Bit 19 : “1” when data is valid.
==> Tag bit in slot 0 is also set to “1” when data is output.
Bit 18-16 : Measurement mode (A2-0 bit)
Bit 15-4 : 12bit ADC data
In this mode, ADFLT bit is ignored. Even if ADFLT bit is set to “1”, four data average is not executed. The AK4650
supports the following three measurement modes:
(1)
Sequential measurement of set item
(2)
XY measurement mode
(3)
XYZ measurement mode

Table 51. 12bit ADC measurement mode setting
4-1. Sequential measurement of set item
The AK4650 measures the item set by A2-0
and
SER bits sequentially, and outputs the results via slot. When 12bit ADC
is powered-down, bit 19 is “0”.
(1)
When SLOT bit = “1”, pen touch waiting state (PM12AD bit = “0” and PINTE bit = “1”) should set.
(2)
When the controller receives PEN Interrupt, the controller should set PM12AD bit = “1”. Then data is output via slot.
(3)
If 12bit ADC is powered-up by setting PM12AD bit = “1” and measurement item is set by A2-0 and SER bits, then
the set item is sequentially measured after the wait time set by DLY3-0 bits.
If the measurement is not completed in one SYNC period, bit 19 (ADE) is “0”.
