2.2.4.1
An internal power-on reset process is initiated during power-up. When VDD has reached approximately 2.6 V, the
internal reset process begins and continues for 300 ms maximum if REFCLK is applied. If REFCLK is not present,
the CX28380 remains in the reset state.
2.2.4.2
Hard reset is initiated by bringing the RESET pin active (low). Once initiated, the internal reset process completes
in 5 µs maximum. If the RESET pin is held active continuously, the clock and data outputs and the IRQ pin remain
three-stated. The following output pins are forced to high impedance while RESET is held active:
RLOS[1:4] are forced high and JATERR[1] is forced low.
2.2.4.3
In Host Mode, soft reset is initiated by writing a one to the RESET bit in the Global Configuration register [addr 01].
The RESET bit is self-clearing. Once initiated, the internal reset process completes in 5 µs maximum and the
device enters normal operation.
