10.8 Start-Up Sequence
Upon the release of a POR or BOR, the following must occur before the device will begin executing:
- Power-up Timer runs to completion (if enabled).
- MCLR must be released (if enabled).
The Power-up Timer runs independently of MCLR Reset. If MCLR is kept low long enough, the Power-up Timer will expire. Upon bringing MCLR high, the device will begin execution after 10 FOSC cycles (see Figure 10-3). This is useful for testing purposes or for synchronizing more than one device operating in parallel.
