3.5.2 I/O signal functions

3 - 13
I/O signal functions of the A1S66ADA are explained below.
(1) X00 to X0B, X10 to X1B, X20 to X2B, X30 to X3B: Digital output
value
The A/D converted digital values in CH3 to CH6 are stored in Xn0 to XnB as
binary data, as shown below:
XnB XnA Xn9
b11 b10 b9
(Example) When the digital output value in CH3 is 2000 (H07D0)
XnB XnA Xn9
0 1 1
7
(2) Y00 to Y0B, Y10 Y1B: Digital value setting
The digital values to be D/A converted in CH1 and CH2 are set in Yn0 to YnB as
binary data, as shown below:
YnB YnA Yn9
b11 b10 b9
(Example) When the digital value in CH2 is set to 2500 (H09C4)
YnB YnA Yn9

(3) Y0F, Y1F: CH1, CH2 D/A conversion value output enable flag
Outputting the D/A converted analog value to outside the module may be
enabled or disabled.
ON·······Output enabled
The D/A converted analog value is output externally.
OFF·····Output disabled
The analog value 0 V/0 mA is output.
