In User mode the instructions behave as follows:
MSR CPSR_all,Rm ; CPSR[31:28] <- Rm[31:28]
MSR CPSR_flg,Rm ; CPSR[31:28] <- Rm[31:28]
MSR CPSR_flg,#0xA0000000 ; CPSR[31:28] <- 0xA
;(set N,C; clear Z,V)
MRS Rd,CPSR ; Rd[31:0] <- CPSR[31:0]

In privileged modes the instructions behave as follows:
MSR CPSR_all,Rm ; CPSR[31:0] <- Rm[31:0]
MSR CPSR_flg,Rm ; CPSR[31:28] <- Rm[31:28]
MSR CPSR_flg,#0x50000000 ; CPSR[31:28] <- 0x5
;(set Z,V; clear N,C)
MRS Rd,CPSR ; Rd[31:0] <- CPSR[31:0]
MSR SPSR_all,Rm ;SPSR_<mode>[31:0]<- Rm[31:0]
MSR SPSR_flg,Rm ; SPSR_<mode>[31:28] <- Rm[31:28]
MSR SPSR_flg,#0xC0000000 ; SPSR_<mode>[31:28] <- 0xC
;(set N,Z; clear C,V)
MRS Rd,SPSR ; Rd[31:0] <- SPSR_<mode>[31:0]
