Atmel ATmegaA is a powerful microcontroller that provides a highly flexible and cost effective solution to many embedded control applications. As inputs, Port A pins that are externally pulled low will source current if the pull-up resistors are activated. The Port A pins are tri-stated when a reset condition becomes active, even if the clock is not running.
Port A also serves the functions of various special features of the ATmegaA as listed on page As inputs, Port E pins that are externally pulled low will source current if the pull-up resistors are activated. The Port E atmega18a are tri-stated when a reset condition becomes active, even if the clock is not running.
Port E also serves the functions of various special features of the ATmegaA as listed on page PEN has no function during normal operation.
Shorter pulses are not guaranteed to generate a reset. A comprehensive set of development tools, application notes, and datasheets are available for download on http: Dimensions D1 and E1 do not atmegw128a mold protrusion.
Allowable protrusion is 0. Dimensions D1 and E1 are maximum plastic body size dimensions including mold mismatch. Lead coplanarity is 0.
