11.13.10 INTCTRL - Interrupt Control Register
8210B–AVR–04/10
OUTTGL - Data Output Value Toggle Register
IN - Data Input Value Register
• Bit 7:0 - OUTCLR[7:0]: Data Output Value Clear
This register can be used instead of a Read-Modify-Write to set the output value on individual
pins to zero. Writing a one to a bit will clear the corresponding bit in the OUT register. Reading
this register will return the value in the OUT register.
• Bit 7:0 - OUTTGL[7:0]: Port Data Output Value Toggle
This register can be used instead of a Read-Modify-Write to toggle the output value on individual
pins. Writing a one to a bit will toggle the corresponding bit in the OUT register. Reading this reg-
ister will return the value in the OUT register.
• Bit 7:0 - IN[7:0]: Data Input Value
This register shows the value present on the pins if the digital input driver is enabled. INn shows
the value of pin n on the port.
• Bit 7:4 - Reserved
These bits are unused and reserved for future use. For compatibility with future devices, always
write these bits to zero when this register is written.
• Bit 3:2/1:0 - INTnLVL[1:0]: Interrupt n Level
These bits enable interrupt request for port interrupt n and select the interrupt level as described
