Register 2: System Exception Interrupt Mask (SYSEXCIM), offset 0x004
The SYSEXCIM register is the interrupt mask set/clear register.
On a read, this register gives the current value of the mask on the relevant interrupt. Setting a bit
allows the corresponding raw interrupt signal to be routed to the interrupt controller. Clearing a bit
prevents the raw interrupt signal from being sent to the interrupt controller.

Reset Description
0x0000.00 Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.

Value Description
0 The FPIXCRIS interrupt is suppressed and not sent to the
interrupt controller.
1 An interrupt is sent to the interrupt controller when the
FPISCRIS bit in the SYSEXCRIS register is set.
