Pin Out Description
The signal naming convention holds that active low signals are named with a “b” suffix.

Description
ARRAYCLKOUT
Digital Output
Programming allows one of the 4 internal clocks
to be presented here.
Configuration mode control pin
0 = Micro Peripheral Interface Mode (Micro)
1 = Boot From Serial ROM (BFR)
Configuration mode control pin
0 = Use Internal Clock (CFG_CLK is an output,
running at 1/8 internal ring oscillator frequency.)
1 = Use External Clock (CFG_CLK is the clock
input to the configuration logic.)
Configuration logic clock
Direction controlled by MODE[2]
SPROM Configuration clock output
1/2 frequency of CFG_CLK.
Data pins used for loading configuration data
and checking status. DATA[0] is used for serial
BFR mode, and the entire byte width is used in
Micro mode.

Configuration Function pins
(BFR mode function, Micro mode function)
F[1] is an Open Drain output. In multi-FPAA
systems, all the ERRb lines can be tied together
to provide a single error indicator.
Op-Amp disable input (normally tied to Vss, not
usually utilized in systems)
Takes precedence over BFR’s PWRUP input
and Micro’s Function Register Bit Position 4
(Analog Enable)
0 = Analog circuitry enabled
1 = Analog circuitry disabled
