885 +As you can see from the byte parsing table of pattern 7, the seventh byte of the original load is used to display the PA8 pin interrupt flag and status, the eighth byte of the original load is used to display the PA4 pin interrupt flag and status, and the ninth byte of the original load is used to display the PB15 pin interrupt flag and status.
