28 / 48 page  VQ.QW WPPIQPWE CC Confidential Page 28/48 www.x-powers.com Single Cell Li-Battery PWM Charger and Power System Management IC AXP202 Standard 100KHz or 400KHz frequency is supported, and the highest rate can reach 1.2KHz. In addition, multi read and write operation is supported, and the device addresses are 69H (READ) and 68H (WRITE). When certain events occur, AXP202 will inform Host by pulling down the IRQ interrupt mechanism, and the interrupt state will be reserved in interrupt state registers (See registers REG48H, REG49H, REG4AH, REG4BH and REG4CH). The interrupt can be cleared by writing 1 to corresponding state register bit. When there is no interrupt, IRQ output will be pulled high (51K resistance higher through the external). Each interrupt can be masked via interrupt control registers (Refer to registers REG40H, REG41H, REG42H, REG43H, and REG44H).
