CCR I bit 1

Set port mode register bit

Execute NOP instruction

Interrupts masked. (Another possibility
is to disable the relevant interrupt in
interrupt enable register 1.)

After setting the port mode register bit,
first execute at least one instruction
(e.g., NOP), then clear the interrupt
request flag to 0

Interrupt mask cleared

Clear interrupt request flag to 0

Notes on Interrupt Request Flag Clearing Methods

Either of the following methods should be used for flag clearing in the interrupt request registers
(IRR1, IRR2, IWPR).

Method 1

Clear the interrupt request flag with a BCLR instruction. (Recommended method)

Sample coding for clearing IRRI1 (bit 1 of IRR1):

BCLR #1,@IRR1:8

Method 2

Write data to the interrupt request register with 0 for the relevant interrupt request flag and 1s for
the other flags. (Faster execution than Method 1)

Sample coding for clearing IRRI1 (bit 1 of IRR1):

MOV.B #B'11111101,R1L

MOV.B R1L,@IRR1:8
