Description
A20 — External memory address line 20.
A21 — External memory address line 21.
A22 — External memory address line 22.
A23 — External memory address line 23.
XCLK — Clock output.
CS3 — Low-active Chip Select 3 signal.
(Bank 3 addresses range 8300 0000 - 83FF FFFF)
CS2 — Low-active Chip Select 2signal.
(Bank 2 addresses range 8200 0000 - 82FF FFFF)
CS1 — Low-active Chip Select 1 signal.
(Bank 1 addresses range 8100 0000 - 81FF FFFF)
WE — Low-active Write enable signal.
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).
TD1: CAN1 transmitter output.
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.
Analog Ground: 0 V reference. This should nominally be the same voltage
as V
PLL Analog Ground: 0 V reference. This should nominally be the same
voltage as V
1.8 V Core Power Supply: This is the power supply voltage for internal
circuitry.
Analog 1.8 V Core Power Supply: This is the power supply voltage for
internal circuitry. This should be nominally the same voltage as V
be isolated to minimize noise and error.
3.3 V Pad Power Supply: This is the power supply voltage for the I/O ports.
Analog 3.3 V Pad Power Supply: This should be nominally the same voltage
as V
