This reset condition occurs in PLL clock mode when the LOLRE bit in the
SYNCR register 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.
A software reset occurs the SOFTRST bit is set. If the RESET pin 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.
The LVD reset will occur when the supply input voltage drops below V
(minimum).
The reset logic control flow is shown in
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.
