47
MD
Mode selection pin. Connected in parallel with the
onboard MD button. Use an open collector circuit
to control this line as pressing the MD button
short-circuits the line onto the GND.
48
<TEST PIN>
Leave this pin unconnected.
49
RST
Reset line, active high.
50
PM
PLL control line (HIGH- PLL ON, LOW- PLL OFF).
51
SR
Red status LED control line. Also connected to the
onboard LED. Maximum load on this line is 3mA.
Use a buffer (logic gate) if higher current is
desired.
52
SG
Green status LED control line. Also connected to
the onboard LED. Maximum load on this line is
3mA. Use a buffer (logic gate) if higher current
is desired.
53
(1,2)
GPIO46
General-purpose I/O line 46.
54
(1,2)
GPIO45/CO
General-purpose I/O line 45 (does not belong to
any 8-bit port);
square wave output line.
55
(1,2)
GPIO48
General-purpose I/O line 48 (does not belong to
any 8-bit port).
56
(1,2)
GPIO47
General-purpose I/O line 47 (does not belong to
any 8-bit port).
57
DBGRX
RX line of debug serial port (details to be
published).
58
3.3V
Output of the onboard 3.3V regulator. Can supply
up to 1A of current to external devices (1.3A
without the WA2000).
This line can also be used to power the EM1001.
Use regulated 3.3V power source only!
59
DBGTX
TX line of debug serial port (details to be
published).
60
VIN
Switching regulator supply voltage in the 8-20V
range. The regulator generates 3.3V power for the
onboard circuitry, WA2000, and external devices
connected to the 3.3V line.
There is no need to use this input if the EM1001 is
powered directly through the 3.3V line.
This line is also connected to the positive terminal
on the power jack.
61
(4)
GND
System ground.
62
(4)
3.3V
3.3V power available on this pin. Do not connect
to the power source.
63
(1,2,4)
GPIO49
General-purpose I/O line 49 (does not belong to
any 8-bit port).
64
---
No connection.
65
(1,2,4)
GPIO50
General-purpose I/O line 50 (does not belong to
any 8-bit port).
66
