B. The PLL block responds to the
HALT signal. SYSCLKOUT is held for the number of cycles indicated below before
oscillator is turned off and the CLKIN to the core is stopped:
- 16 cycles, when DIVSEL =
00 or 01
- 32 cycles, when DIVSEL =
10
- 64 cycles, when DIVSEL =
11
This delay enables the CPU pipeline and any other pending operations to
flush properly. If an access to XINTF is in progress and its access time is
longer than this number then it will fail. It is recommended to enter HALT mode
from SARAM without an XINTF access in progress.
