A16
The A16 pin on the PORTG/AUX connector is connected to A16 (address pin 16) on the
SRAM. ATmega103(L) and ATmega128(L) support up to 60 KB of external SRAM. The
STK501 SRAM footprint is for a 128 KB SRAM. Implementing software control of the
A16 line will increase the memory range from 64 KB to 128 KB. This line is pulled low by
default, addressing the lower 64 KB of the SRAM.

SRAMEN
The SRAMEN pin on the PORTG/AUX connector is connected to the Chip-enable (CE)
pin of the SRAM. This signal controls if the SRAM should be enabled or not. To enable
the SRAM, a low level should be applied to this pin. This pin is pulled high by default,
through a 10 k ? resistor. Figure 2-10 shows a simplified block schematic on how the
SRAM interface is implemented. Figure 2-11 shows how to enable the SRAM by short-
ing SRAMEN and GND on the PORTG/AUX connector using one of the supplied
jumpers.
This signal can also be controlled by software or by some external control logic.
