̍ɽGPIO Data Acquisition
ɾ[Pin DIR(PAGE1,GPDIR)]: Check the box of “Direction” in the GPIO Pin Assignment, then click [Write]
button. And click [Read] button, then display the current setting in Hex. [Pin DIR
(PAGE1, GPDIR)] corresponds to “GPIO Pin Direction Register” of the
AK4184A’s register.
ɾ[Pin Pull-up(PAGE1, GPPU)]: Check the box of “Pin Pull-up” in the GPIO Pin Assignment, then click [Write]
button. And click [Read] button, then display the current setting. [Pin Pull-up
(PAGE1, GPPU)] corresponds to “GPIO Pin Pull-up Register” of the AK4184A’s
register.
ɾ[Pin State(PAGE1, GPPS)]: Check the box of “Pin State”, then click [Write] button. [Pin State (PAGE1,
GPPS)] corresponds to “GPIO Pin State Register” of the AK4184A’s register.
ɾ[Pin Set/Clear(PAGE1, GPSCR)]: Check the box of “Pin Set/Clear” in the GPIO Pin Assignment, then click
[Write] button. [Pin Set/Clear (PAGE1, GPSCR)] corresponds to “GPIO Pin State
Register” of the AK4184A’s register.
ɾ[Pin Level(PAGE0, GPLR)]: Click [Read] button in the GPIO Pin Assignment, then read “GPIO Pin Level
Register” status and display the input level in “Pin Level”
< Example ʵ GPIO Input >
a. Set the jumper pins of JP9~JP16 (GP0~GP7) to become “IN”.
b. Check the box of “Direction” (GP0~GP7) to become “Input”, and click [Write] button of “Pin DIR
(PAGE1, GPDIR)”.
c. Set the DIP SW (S1) to become either “H” or “L”.
d. Click [Read] button of “Pin Level (PAGE0, GPLR)”.
e. Display the input level in “Pin Level”.
