Figure 10-1. Power-on Timings
Note: Indicated timings are typical values and could vary depending on the installed firmware and actual configuration. Timings after release of MCLR are similar to above. The Bootloader mode can be entered in the first 600 ms after Reset and will be aborted about 400 ms after the latest message not recognized by the bootloader itself (see ‘MGC3140/MXG3141 Library Interface Guide’ - DS40001875C document for a description of commands available in Bootloader mode).
