2.4.3 The Program Status Registers
The ARM7TDMI contains Current Program Status Register (CPSR), plus five Saved
Program Status Register (SPSRs) for use by exception handlers. These registers
hold information about the most recently performed ALU operation control the
enabling and disabling of interrupts set the processor operating mode
The arrangement of bits is shown in Fig. 2.7 Program status register format.
