i)
In the interrupt mode (when the IT/PLS
1 bit is 1)
(i-1)
When DP is 0:
The IRQ FLAG1 bit is read
Interrupt timing
"0"
"1"
"0"
IRQ FLAG1
IRQ FLAG0
(i-2)
When DP is 1:
The IRQ FLAG1 bit is read
Interrupt timing

IRQ FLAG1
IRQ FLAG0
122s
"1"
Note:
When the IRQ FLAG
1 bit is read within the 122
s interval with the MASK
1 bit set at 1, it is not
cleared. The IRQ FLAG
1 bit is cleared after the
122
s interval ends.
ii)
In the periodic pulse output mode (when the IT/PLS
1 bit is 0)
0 is written in the IRQ FLAG1 bit
with DP set at 0
Output timing
