3.3V REF 14.318Mhz clock output.
Latched input for FS0 at initial power up for H/W selecting the
output frequency, Latched voltage level refers to Vil_FS and
Vih_FS voltage level. This is internal 120K pull down.
3.3V REF 14.318Mhz clock output.
24MHz (default) or 48MHz clock output, In power on reset
period, it is a hardware-latched pin, and it can be R/W by I2C
control after power on reset period. Select by register 5 bit 7.
Latched input for 24MHz or 48MHz select pin. This is internal
120K pull up default 24MHz. In power on reset period, it is a
hardware-latched pin, and it can be R/W by I2C control after
power on reset period. Select by register 5 bit 7.
48MHz clock output for USB.
Latched input for FS1 at initial power up for H/W selecting the
output frequency. Latched voltage level refers to Vil_FS and
Vih_FS voltage level. This is internal 120K pull up.
