1.4 Reset
To initialize the NJU26125, RESETb pin should be set Low level during some period. After some period of
Low level, RESETb pin should be High level. This procedure starts the initialization of the NJU26125. After
the power supply and the oscillation of the NJU26125 becomes stable, RESETb pin must be kept
Low-level more than t
After RESETb pin level goes to "High" (after reset release), a setup of the internal hardware of a Serial
Host Interface completes NJU26125 within 10msec. Then, it will be in the state which can communicate.
Don’t stop the supply of a clock while operating. NJU26125 installs PLL circuit internally. If the supply of a
clock is stopped, PLL circuit cannot be sent a clock to the inside and NJU26125 does not operate normally.
If supply of a clock is stopped or the NJU26125 is reset again, putting a normal clock into CLK terminal, the
period RESETb terminal of t
