GPIO4
111
I/O8
General Purpose I/O:
This pin may be used either as input, edge sensitive interrupt
input, or output.
GPIO5

I/O8
General Purpose I/O:
This pin may be used either as input, edge sensitive interrupt
input, or output.
GPIO6/
ROMEN

IPU
GPIO6, ROMEN:
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 USB2227/USB2228 uses this external bus for
program execution.
When this pin is left unconnected or pulled high by a weak pull-
up resistor, the USB2227/USB2228 uses the internal ROM for
program execution.
