The Force Event Register is not a physically implemented register. Rather, it is an address at which the Error
Interrupt Status register can be written. The effect of a write to this address will be reflected in the Error Interrupt
Status Register if the corresponding bit of the Error Interrupt Status Enable Register is set.
• Writing 1: set each bit of the Error Interrupt Status Register
• Writing 0: no effect
Note: By setting this register, the Error Interrupt can be set in the Error Interrupt Status register. In order to generate
interrupt signal, both the Error Interrupt Status Enable and Error Interrupt Signal Enable shall be set.
