TPS65910 exercising interrupt using GPIO_CKSYNC

Other Parts Discussed in Thread: TPS65910, OMAP-L138

Has anyone used the GPIO input high-to-low or low-to-high to generate a "test" interrupt on the TPS65910?

I need to see if the INT output pin can be detected from an OMAP-L138. If I use an output from the processor as input to GPIO_CKSYNC pin, can I use that to generate an "interrupt" that will then take the INT pin from an inactive state to an active state? Do I then clear that active interrupt with an I2C command?

    Hi Todd,

    Yes, if the DCDCKEXT = 0, GPIO_CFG =0, and the GPIO0_R/F_IT_MSK bits are not set, then any rising or falling edge on GPIO_CKSYNC will generate an interrupt on INT1.

    The particular interrupt can be cleared by writing 1 to the status bit in INT_STS2_REG.
