Reset
This LSI includes a hard reset function using the external XRESET terminal and a soft reset function
using register settings.
4.2.1
Hard Reset
Start up from reset status when power is turned on, then cancel the reset after confirming
power on.
4.2.2
Soft Reset
The USB circuits can be reset, or internal USB analog macros can be reset individually, via
software. The ChipReset.AllReset bit initializes all circuits except the CPUIF_MODE
register, or the ChipReset.ResetMTM bit for each port is used to reset individual port USB
analog macros. Note that the USB analog macro should be reset only when in the sleep
state.
4.3
Clock
This LSI incorporates an internal oscillator and feedback resistor (1 M) and supports clock
generation with an external oscillator. The oscillator frequency can be set to 12 MHz or 24 MHz via
register settings.
Figure 4-2 shows a typical connection configuration for an oscillation circuit. Cd, Cg, and Rd in the
oscillator circuit shown must be matched for the specific oscillator. Contact the oscillator
manufacturer to obtain circuit constants.
