• Description: 64/100-pin General Purpose, 32-bit Flash Microcontrollers
• Manufacturer: Microchip Technology Inc.

TABLE 8-3:
8.4.1
The delay between the end of a Reset event and when
the device actually begins to execute code is determined
by two main factors: the type of Reset and the system
clock source coming out of the Reset. The code execu-
tion start time for various types of device Resets are
summarized in Table 8-4. Individual delays are
characterized in Section 29.2 “AC Characteristics and
Timing Parameters”.
