PENIRQN
O
Pen Interrupt Output
This pin should be pulled up via a 100k-ohm resistor. This pin is “L” during the pen down on
pen interrupt enable state with CSN =“H” otherwise this pin is “H”. This pin is “H” during pen
interrupt disable state with the CSN = “H” regardless pen touch. See
Power-down Control and
Pen Interrupt for the reference.
12
DOUT
O
Serial A/D Data Output
Output A/D data serially at the falling edge of DCLK. MSB is output at the falling edge of
BUSY signal.
Output “L” at CSN= “L” during A/D data does not output.
This pin is Hi-Z state at CSN=”H”
13
BUSY
O
BUSY Output
This pin goes to low at CSN = “L”. BUSY signal is “H” only for the period between the falling
edge of 8
th DCLK and the falling edge of 9th DCLK.
This pin is Hi-Z state at CSN= “H”
14
DIN
I
Serial Data Input
Inputs 8-bit control command data serially when CSN= “L”
AK4181A latches at the rising edge of DCLK. Must keep “L” while not issuing commands.
15
CSN
I
Chip Select Input
Enables writing data to the registers when CSN= “L”.
