NAME

FUNCTION
IFSEL[2:0]
I
Microprocessor Interface Select. When no microprocessor interface is selected, all
microprocessor interface inputs are ignored and internally pulled low, and all microprocessor
interface outputs are put in a high-impedance state. See Section 6 for details.
000 = no microprocessor interface (must set HW = 1 and use hardware interface)
001 = reserved
010 = SPI serial interface, address and data MSB first
011 = SPI serial interface, address and data LSB first
100 = 8-bit parallel interface, Intel style (
CS, RD, WR control signals)
101 = 8-bit parallel interface, Motorola style (
CS, R/W, DS control signals)
110 = 16-bit parallel interface, Intel style (
CS, RD, WR control signals)
111 = 16- bit parallel interface, Motorola style (
CS, R/W, DS control signals)
HW
Ipd
Hardware Interface Enable. When the hardware interface pins are disabled, all hardware
control inputs are ignored and internally pulled low, and all hardware status outputs are put in a
high impedance state. See Section 6 for details.
0 = Hardware interface pins disabled
1 = Hardware interface pins enabled
TEST
I
Factory Test Enable (Active Low). This pin enables the internal scan test mode when low.
For normal operation tie high. This is an asynchronous input.
HIZ
I
High-Impedance Test Enable (Active Low). This signal is used to enable testing. When this
signal is low while
JTRST is low, all the digital output and bidirectional pins are placed in the
high-impedance state. For normal operation this signal is high. This is an asynchronous input.
RST
Ipu
Reset (Active Low, Open Drain). When this global asynchronous reset is pulled low, all
internal circuitry is reset and all internal registers are forced to their default values. The device
is held in reset as long as
RST is low. RST should be held low for at least two reference clock
cycles. See Section 8.11.
RESREF
Oa
Reference Resistor. This pin is tied to VSS through a 10k
Ω ±1% resistor. This accurate
resistor is used to calibrate on-chip resistor values including internal transmit and receive
termination resistors.
