Symbol
EXTIICINT
Address
02D616
At reset
0016
Bit symbol
Reserved bits
Bit name
Must set to "0."
Function
RW
EXTIICINT0
EXTIICINT1
ACK interrupt control bit
(Note 1)
0000: Interrupt prohibition (Note 2)
0101: Interrupt permission
Other: Must not be set
EXTIICINT2
EXTIICINT3
Please set TA4IC (Note 3) when
you use it by "Interrupt permission".
Notes 1: Timer A4 and multi master I²C (ACK) interrupt, the vector and the interrupt control register
are shared. Please make it to (b7, b6, b5, b4) = (0, 1, 0, 1) when you use multi-master I²C
(ACK) interrupt.
Notes 2: Please set 00002 when you use the interrupt of timer A4.
Notes 3: Please refer to "Figure 6.3 interrupt control register" of "6.5 interrupt control".
Notes 4: Please change in the part where multi-master I²C (ACK) and timer A4 interrupt request are
not generated in the I²C0 interrupt control register.
Notes 5: Please permit interrupt after making IR bit of timer A4 (TA4IC) "0" (the interrupt request none)
after EXTIICINTi (i = 0 to 3) is changed.
