Example 1:
INT_SWITCH1:
FCLR
I
; Disable interrupts.
AND.B
#00h, 0055h
; Clear TA0IC int. priority level and int. request bit.
NOP
; Four NOP instructions are required when using HOLD function.
NOP
FSET
I
; Enable interrupts.
Example 2:
INT_SWITCH2:
FCLR
I
; Disable interrupts.
AND.B
#00h, 0055h
; Clear TA0IC int. priority level and int. request bit.
MOV.W MEM, R0
; Dummy read.
FSET
I
; Enable interrupts.
Example 3:
INT_SWITCH3:
PUSHC FLG
; Push Flag register onto stack
FCLR
I
; Disable interrupts.
AND.B
#00h, 0055h
; Clear TA0IC int. priority level and int. request bit.
POPC
FLG
; Enable interrupts.
When a instruction to rewrite the interrupt control register is executed but the interrupt is disabled,
the interrupt request bit is not set sometimes even if the interrupt request for that register has
been generated. This will depend on the instruction. If this creates problems, use the below in-
structions to change the register.
Instructions : AND, OR, BCLR, BSET
(5) Rewrite the interrupt control register
To rewrite the interrupt control register, do so at a point that does not generate the interrupt
request for that register. If there is possibility of the interrupt request occur, rewrite the interrupt
control register after the interrupt is disabled. The program examples are described as follow:
