7.16 Status Registers

The AS8650 has three Flag status registers and one RESET reason register. The Flag status registers indicate the current status of flags which

are related to respective interrupt source registers. The Flag status registers are Bus status register, Temperature status register and Supply

status register. The microprocessor can read these registers any time to check the status of device. The function of each flag is listed in register

space description in subsequent sections.

A RESET reason register indicates the reasons for RESET generation. Once the RESET pin goes low, the reason of this reset event is stored in

RESET reason register. When RESET is released microprocessor can read this register to know the cause for last RESET signal. The RESET

reason register is cleared once microprocessor reads this register through read operation. The bits functionality of this register is explained in

register space description table.
