Access:
• UPLLEN: UTMI PLL Enable
0 = The UTMI PLL is disabled.
1 = The UTMI PLL is enabled.
When UPLLEN is set, the LOCKU flag is set once the UTMI PLL startup time is achieved.
• UPLLCOUNT: UTMI PLL Start-up Time
Specifies the number of Slow Clock cycles multiplied by 8 for the UTMI PLL start-up time.
• BIASEN: UTMI BIAS Enable
0 = The UTMI BIAS is disabled.
1 = The UTMI BIAS is enabled.
• BIASCOUNT: UTMI BIAS Start-up Time
Specifies the number of Slow Clock cycles for the UTMI BIAS start-up time.
