(When “0” is written to IRQ FLAG bit, at that time, STD.P
output becomes open without awaiting automatic return.)
IN TRT/STND BIT = "0"
b) ITRPT/STND (D1) (INTERRUPT/STANDARD PULSE)
This is a bit which gives the meaning for STD.P output. When this bit="1", the request for
interrupt is outputted at the STD.P output and when this bit="0", a fixed cycle waveform with
a low-level pulse width of 7.8125ms is present at the STD.P output. However, at this time,
the MASK bit must equal 0, while the period in either modes is determined by t0 (D2) and
t1(D3) of register CE.
c) t0 (D2), t1 (D2) (time 0, 1)
When ITRPT/STND bit="1", this bit determines the interrupt period. When ITRPT/
STND bit="0", this bit determines the period of fixed timing waveform. The periods are
shown in the table below.

The timing of the STD.P output designated by t1 and t2 occurs at the moment that a carry
occurs to a clock digit.
