System Control
NRND: Not recommended for new designs.
Register 4: Interrupt Mask Control (IMC), offset 0x054
This register contains the mask bits for system control raw interrupts. A raw interrupt, indicated by
a bit being set in the Raw Interrupt Status (RIS) register, is sent to the interrupt controller if the
corresponding bit in this register is set.

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.

MOSC Power Up Interrupt Mask
Value Description
1 An interrupt is sent to the interrupt controller when the
MOSCPUPRIS bit in the RIS register is set.
0 The MOSCPUPRIS interrupt is suppressed and not sent to the
interrupt controller.
