Description
Multipurpose I/O bank 3
MPIO3_0 = INT0/ to
microcontroller, if 0xFF05 bit 0
is set (active low).
MPIO3_1 = INT1/ to
microcontroller, if 0xFF05 bit 0
is set (active low).
MPIO3_2 = TXD from
microcontroller, if 0xFF05 bit 1
is set.
MPIO3_3 = RXD to
microcontroller, if 0xFF05 bit 1
is set.
Open drain multipurpose LED
bank 0 outputs. Any unused
LED outputs must be tied to

Open drain multipurpose LED
bank 1 outputs. Any unused
LED outputs must be tied to
V
Open drain multipurpose LED
bank 2 outputs. Any unused
LED outputs must be tied to
V
This pin should be tied LOW
during normal operation.
When this signal is tied HIGH,
the internal clock will be the
same as the external. When
LOW, the external frequency is
divided by 2.
