DIR – Data Direction Register
DIRSET – Data Direction Set Register
DIRCLR – Data Direction Clear Register
DIRTGL – Data Direction Toggle Register
• Bit 7:0 – DIR[7:0]: Data Direction
This register sets the data direction for the individual pins of the port. If DIRn is written to one,
pin n is configured as an output pin. If DIRn is written to zero, pin n is configured as an input pin.
• Bit 7:0 – DIRSET[7:0]: Port Data Direction Set
This register can be used instead of a read-modify-write to set individual pins as output. Writing
a one to a bit will set the corresponding bit in the DIR register. Reading this register will return
the value of the DIR register.
• Bit 7:0 – DIRCLR[7:0]: Port Data Direction Clear
This register can be used instead of a read-modify-write to set individual pins as input. Writing a
one to a bit will clear the corresponding bit in the DIR register. Reading this register will return
the value of the DIR register.
