Power-up period: Internal voltage regulator enabled | TPU | — | 400 | 600 | us |
System delay period:
Time required to reload device configuration fuses plus clock delay before first instruction is fetched | TSYSDLY | — | 1.2 | — | us |
MCLR minimum pulse width | TMCLR | 2 | — | — | us |
BOR pulse width | TBOR | — | 1 | — | us |
Note:
- These parameters are characterized, but not tested in manufacture.
- Data in Typical column is at 3.3V, 25°C, unless otherwise stated.
Note: Indicated timings are typical values
and may vary depending on installed firmware and actual configuration.
Timings after release of MCLR are similar to above.
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 bootloader itself (see the document 40001875C – "MGC3140/MGX3141 Library Interface Guide" for a description of commands available in Bootloader mode.
