AXP209
Enhanced single Cell Li-Battery and Power System Management IC
Figure 2: Multi Read and Write
Host can access the AXP209 registers via the TWSI interface, and the operation timing is shown
above. Standard 100KHz or 400KHz frequency is supported, and the highest rate can reach 1.2MHz.
In addition, multi read and write operation is supported, and the device addresses are 69H (READ)
and 68H (WRITE).
When certain events occur, AXP209 will inform the Host by pulling down the IRQ interrupt line, and
the interrupt state will be stored 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 (by 51K external pull-up resistor).
Each interrupt can be masked via interrupt control registers (Refer to registers REG40H, REG41H,
REG42H, REG43H, and REG44H).
