Reset Controller Module
approximately 512 cycles after the PLL has acquired lock. The part then exits reset and begins
operation.
10.4.1.5 Loss-of-Lock Reset
This reset condition occurs in PLL clock mode when the LOLRE bit in the SYNCR is set and the
PLL loses lock. The reset controller asserts RSTOUT for approximately 512 cycles after the PLL
has acquired lock. The part then exits reset and resumes operation.
10.4.1.6 Software Reset
A software reset occurs when the SOFTRST bit is set. If the RESET is negated and the PLL has
acquired lock, the reset controller asserts RSTOUT for approximately 512 cycles. Then the part
exits reset and resumes operation.
10.4.2 Reset Control Flow
The reset logic control flow is shown in
Figure
10-4. In this figure, the control state boxes have
been numbered, and these numbers are referred to (within parentheses) in the flow description that
follows. All cycle counts given are approximate.
