DATASHEET
GPIO6, ROMEN,
Memory Address 16
GPIO6/ROMEN
/MA16
IPU
This pin has an internal weak pull-up resistor that is
enabled or disabled by the state of nRESET.
The pull-up is enabled when nRESET is active.
The pull-up is disabled, when the nRESET is inactive
(some clock cycles later, after the rising edge of
nRESET).
The state of this pin is latched internally on the rising
edge of nRESET to determine if internal or external
program memory is used.
The state latched is stored in ROMEN bit of GPIO_IN1
register.
I/O8
After the rising edge of nRESET, this pin may be used
as GPIO6 or RXD.
When pulled low via an external weak pull-down
resistor, an external program memory should be
connected to the memory data bus. The
USB2229/USB2230 uses this external bus for program
execution.
When this pin is left unconnected or pulled high by a
weak pull-up resistor, the USB2229/USB2230 uses the
internal ROM for program execution.
I/O8
For Bank Switching support, MA16 addresses the
external 128k memory above the standard 64k range
(the upper 64k is mapped into the 64k addressable
ROM space)

GPIO: This pin may be used either as input, edge
sensitive interrupt input, or output.

General Purpose
I/O
GPIO12
I/O8
These pins may be used either as input, or output.
RESET input
nRESET
IS
This active low signal is used by the system to reset the
chip. The active low pulse should be at least 1
μ
s wide.
TEST Input
nTEST[1:0]
I
These signals are used for testing the chip. User should
normally tie them high externally, if the test function is
not used.
