Table 37. PLL Control/Status Register (PLLCSR) Description<br />
BIT # NAME DESCRIPTION<br />
31:7 Reserved Reserved. Read-only, writes have no effect.<br />
Clock Input Stable. This bit indicates if the clock input has stabilized.<br />
6 STABLE<br />
0 – Clock input not yet stable. Clock counter is not finished counting (default).<br />
1 – Clock input stable.<br />
5:4 Reserved Reserved. Read-only, writes have no effect.<br />
Asserts RESET to PLL<br />
3 PLLRST<br />
0 – PLL Reset Released.<br />
1 – PLL Reset Asserted (default).<br />
2 Reserved Reserved. The user must write a “0” to this bit.<br />
1 PLLPWRDN<br />
0 PLLEN<br />
Select PLL Power Down<br />
0 – PLL Operational (default).<br />
1 – PLL Placed in Power-Down State.<br />
PLL Mode Enable<br />
0 – Bypass Mode (default). PLL disabled.<br />
Divider D0 and PLL are bypassed. SYSCLK1/SYSCLK2/SYSCLK3 are divided down<br />
directly from input reference clock.<br />
1 – PLL Enabled.<br />
Divider D0 and PLL are not bypassed. SYSCLK1/SYSCLK2/SYSCLK3 are divided down<br />
from PLL output.<br />
