2.1.3.5.2 Interrupt Program Status Register
2.1.3.5.3 Execution Program Status Register
2011-02-04 - d0002_Rev1.00
The IPSR contains the exception type number of the current Interrupt Service Routine (ISR). See the
register summary in Table 2.2 (p. 7) for its attributes. The bit assignments are:
Table 2.5. IPSR bit assignments
The EPSR contains the Thumb state bit, and the execution state bits for either the:
• If-Then (IT) instruction
• Interruptible-Continuable Instruction (ICI) field for an interrupted load multiple or store multiple
See the register summary in Table 2.2 (p. 7) for the EPSR attributes. The bit assignments are:
Table 2.6. EPSR bit assignments
Attempts to read the EPSR directly through application software using the MSR instruction always return
zero. Attempts to write the EPSR using the MSR instruction in application software are ignored. Fault
