hi,

I need some more information regarding the interrupts triggering in the uPSD3200 .

I don't know if INT0 and INT1 are triggered by positive level/edge (refer to page 38 of the uPSD321x data sheet ) or they're triggered by negative level/triggered ( refer bit IT0 of the register TCON at the table37 of datasheet).

Thanks in advance for any comments.

Regards,

Jokin

Hi,

According to Table 37, when IT0 bit is SET, INT0 is triggered at the falling-edge. When IT0 bit is CLEARED, INT0 is triggered at the low-level. IT1 control bit works the same way for INT1.
