Hello,
I am currently looking in to porting some code operating on an MSP430F437IPN device to a device working with an MSP430FR6877. The majority of the other code has been altered to work on the system with no issues but I am having some trouble within the interrupt service routine.
In the original system the following is used
BIC.B #WDTIE, &IE1 ; Disable WDTI
; Output a pulse or check if inter-
; pulse timeout is done.
PUSH R12
PUSH R13
PUSH R14
PUSH R15
CALL #Pulse_Output1
POP R15
POP R14
POP R13
POP R12
BIS.B #WDTIE, &IE1 ; Enable WDTI
RETI
However when converting over based on the SFR in the new MCU with the following:
BIC.B #WDTIE, &SFRIE1 ; Disable WDTI
; Output a pulse or check if inter-
; pulse timeout is done.
PUSH R12
PUSH R13
PUSH R14
PUSH R15
CALL #Pulse_Output1
POP R15
POP R14
POP R13
POP R12
BIS.B #WDTIE, &SFRIE1 ; Enable WDTI
RETI
I get Error[431]: Accessing SFR using incorrect size
on the lines containing BIC.B #WDTIE, &SFRIE1 ; Disable WDTI and BIS.B #WDTIE, &SFRIE1 ; Enable WDTI
Would you happen to know what is going wrong?
