AKD4184A-A Datasheet, PDF (14/25 Pages) Asahi Kasei Microsystems – Evaluation Board Rev.0 for AK4184A

[AKD4184A-A]
< Example ʵ GPIO Output >
a. Set the jumper pins of JP9~JP16 (GP0~GP7) to become “OUT”, and JP19, JP20 is “Open”.
b. Check the box of “Direction” (GP0~GP7) to become “Output”, and click [Write] button of “Pin DIR
(PAGE1, GPDIR)”.
c. Check the box of “Pin Set/Clear” (GP0~GP7) to become either “Set High” or “Clear Low”, and click
[Write] button of “Pin Set/Clear (PAGE1, GPSCR)”.
d. LED of GP0~GP7 turns on when pin level of GP0~GP7 set “High”.
* If you check the box, data becomes “H” or “1”. If not, “L” or “0”.
̎ɽ
PWM control (LED Bias Control)
ɾ[Write PWM Control]: Check the box of “LPU”, “PACT” and select drop down list of “BRV”, “DIV”,
then click [Write PWM Control] button. “LPU”, “BRV”, “PACT” and “DIV”
corresponds to LPU bit, BRV4-0 bits, PACT bit and DIV2-0 bits of AK4184A’s
register (PWM Control Register).
< Example >
a. Check the box of “PACT” to become “Normal Mode”, and “LPU” is “CMOS”.
b. Select any value from drop down list of “BRV” and “DIV”. (“BRV” modulate PWM. If value is small,
become dim. If large, become bright.)
c. When click [Write PWM Control] button, white LED of LED9,10 turns on.
* If you check the box, data becomes “H” or “1”. If not, “L” or “0”.
̏ɽ
Power down control
ɾ[Write PD Control]:
Check the box of “KeyPad PD” and “TSC PD”, then click [Write PD Control]
button. “KeyPad PD” and “TSC PD” corresponds to KPPD bit and TPPD bit of
AK4184A’s register (Power Down Register).
* If you check the box, data becomes “H” or “1”. If not, “L” or “0”.
