BLS3 —
Low-active Byte Lane Select signal (Bank 3).
AIN7 —
A/D converter, input 7. This analog input is always connected to its
pin.
BLS2 —
Low-active Byte Lane Select signal (Bank 2).
AIN6 —
A/D converter, input 6. This analog input is always connected to its
pin.
BLS1 —
Low-active Byte Lane Select signal (Bank 1).
BLS0 —
Low-active Byte Lane Select signal (Bank 0).
Pin not connected.
External Reset input:
A LOW on this pin resets the device, causing I/O ports
and peripherals to take on their default states, and processor execution to
begin at address 0. TTL with hysteresis, 5 V tolerant.
Input to the oscillator circuit and internal clock generator circuits.
Output from the oscillator amplifier.
Ground:
0 V reference.
