i)
In the periodic interrupt mode (when the IT/PLS
1
, bit is 1)
*1
When DP = 1, the open state is not entered until a certain period
passes after an interrupt is generated. (See the description of the C
E
register.)
However, when DP = 1, if the IRQ FLAG
bit is read out within
122
μ
s after an interrupt is generated, it is cleared after 122
μ
s from the
generation of the interrupt.
*2
ii)
In the periodic pulse output mode (when the IT/PLS
1
bit is 0.)
The open status is entered when the IRQ FLAG
1
is read. (*1)
When the IRQ FLAG
1
is read during masking,
IRQ FLAG
1
is not cleared. (*2)
No interrupt occurs
because the MASK
1
bit is 1.

When 0 is written in the IRQ FLAG
1
bit,
the open state is entered without having
to wait for automatic restration
The low level is not output
because the MASK

bit is 1.
