Table 5-16. Setting When Port Pin Is Used for Alternate Function (6/6)
Pin Name Alternate Function
Function Name
P152 ASCK3
P153 TI110
P154 TI111
P155 TO12
P156 TI120
P157 TI121
P176 VM45
Caution When changing the output level of ports 0 and 3 by setting the port function output mode of
ports 0 and 3, the interrupt request flag will be set because ports 0 and 3 also have alternate
functions as external interrupt request inputs. Therefore, be sure to set the corresponding
interrupt mask flag to 1 before using ports 0 and 3 as output pins.
