2. Reset Functions
The ML7065-033 has the following three reset functions:
(1) Reset by the RESETN pin
By asserting the RESETN pin at power-up, the internal circuit can be reset. Refer to the Application
Circuit section for the external circuit for the RESETN pin. Also at a timing other than at power-up, the
internal circuit can be reset by inputting a reset signal to the RESETN pin. After reset, the ML7065-033
enters the normal state after the oscillation circuit and the PLL circuit are stabilized by the clock
stabilization circuit.
(2) Reset by the SRESETN pin
Software reset can be executed from the host by connecting the SRESETN pin to the GPIO pin of the host.
This operation is enabled only when the RESETN pin is deasserted. In a sleep state, the SRESETN pin
functions as a sleep release pin. By asserting the SRESETN pin, the internal circuit can be reset. After
reset, the ML7065-033 enters the normal state after the oscillation circuit and the PLL circuit are stabilized
by the clock stabilization circuit.
(3) Software reset by register access
By setting the SRSTN_INSIDE register to “1” using the RST_CTL1 command, the internal circuit can be
reset. This operation is enabled in states other than a sleep state. After reset, the ML7065-033 enters the
normal state after the oscillation circuit and the PLL circuit are stabilized by the clock stabilization circuit.
