Software Reset
Oscillation Stop Command
Software Reset:
When a “1” is written in this bit, a system reset is executed at the Write pulse. This is
functionally equivalent to a hardware reset.
Oscillation Stop command: The Oscillation circuit of the ML60851C stops and goes into the standby state when
1010b is written in D7 to D4 (that is, when A0h is written in this register).
Once the IC goes into the standby state, to start communication with the USB bus
thereafter, it is necessary to carry out again disconnecting, connecting, and
enumeration.
Even when the Oscillation has stopped, although it is possible to read on write the
registers, it is impossible to read or write the FIFO.
The oscillation can be started again by asserting the RESET pin. The oscillation can
be restarted even by a software reset.
