SIU Interrupt Pending Register 3 (SIPEND3)
6.2.2.2.4
SIU Interrupt Mask Register (SIMASK)
SIMASK is a 32-bit read/write register. Each bit in the register corresponds to an interrupt request bit in
the SIPEND register.
SIMASK2 is a 32-bit read/write register. Each bit in the register corresponds to an interrupt request bit in
the SIPEND2 register.
SIMASK3 is a 32-bit read/write register. Each bit in the register corresponds to an interrupt request bit in
the SIPEND3 register.
When the bit is set, it enables the generation of an interrupt request to the RCPU. SIMASK, SIMASK2,
SIMASK3 are updated by software and cleared upon reset. It is the responsibility of the software to
determine which of the interrupt sources are enabled at a given time.
NOTE
Disable external interrupts in the core prior to changing any interrupt
controller related register (SIMASK, SIPEND, SIEL, or SISR). Refer to
MSR[EE] bit description in
and the note regarding special
handling of the EIC in
Section 6.1.4.4, “Enhanced Interrupt Controller
