Description
1
M0
INPUT
Digital input power ON/reset mode
selection pin, the combination of M0,
M1 and M2, determines the working
mode of the processor. Internally
pulled-down to ground via a 40K
resistor.
2
M1
INPUT
Digital input power ON/reset mode
selection pin, the combination of M0,
M1 and M2, determines the working
mode of the processor. Internally
pulled-down to ground via a 40K
resistor.
3
M2
INPUT
Digital input power ON/reset mode
selection pin, the combination of M0,
M1 and M2, determines the working
mode of the processor. Internally
pulled-down to ground via a 40K
resistor.
4
RESET
INPUT
Digital input reset pin, an active low
pulse greater than 100ns will reset the
processor. Internally pulled-up to 3.3V
via a 40K resistor. 5V tolerant input.
5
GROUND
POWER
Supply ground, be sure to have a well-
grounded connection to avoid noise
over the audio outputs.
6
3.3V
POWER
Main supply voltage: 2.7v-3.5v. Be sure
to use a 10uF and 100nF coupling
capacitors to GND as close as possible
to avoid noise over the audio outputs.
7
Rx - V+
INPUT
Digital input pin MIDI IN. Refer to MIDI
to TTL converter for connections.
Internally pulled-up to 3.3V via a 40K
resistor.
