Function description:
If the condition, H
FREQ
lower than the lower boundary freq.
or higher than the upper boundary freq.,
happens twice continuously, the SOAINT will be activated.
If the HIN is stopped for a certain period, the SOAINT will also be generated.
The no Hsync response time is 512/F
OSC
. (e.x., 51.2us for 10 MHz)
If SOAHDIS = 1, then no upper boundary frequency.
Half Hsync Output
When ENHFO (bit 0 of CTRL3) is set, P4.7 (HFO) will output the same or half frequency from P4.0
(HFI). The divide-by-two operation is done at the falling edge of HFI signal when HFO_HALF (bit 3 of
CTRL3) is set. The polarity of HFO is specified by HF_POL (bit 2 of CTRL3).
