Description
1
ADC5
I
Single-Ended or Differential Analog Input 5/Line Driver Input.
2
VDACOUT
O
Output from DAC Buffer.
3
ADC9
I
Single-Ended or Differential Analog Input 9.
4
ADC10
I
Single-Ended or Differential Analog Input 10.
5
GNDREF
S
Ground Voltage Reference for the ADC. For optimal performance, the analog power supply
should be separated from IOGND and DGND.
6
ADCNEG
I
Bias Point or Negative Analog Input of the ADC in Pseudo Differential Mode. Must be
connected to the ground of the signal to convert. This bias point must be between
0 V and 1 V.
7, 58
AVDD
S
Analog Power.
8
ADC12/LD1TX
I/O
Single-Ended or Differential Analog Input 12/DAC Differential Negative Output.
9
ADC13/LD2TX
I/O
Single-Ended or Differential Analog Input 13/DAC Differential Positive Output.
10, 57
AGND
S
Analog Ground. Ground reference point for the analog circuitry.
11
TMS
I
JTAG Test Port Input, Test Mode Select. Debug and download access.
12
TDI
I

13
P4.6/SPM10
I/O
General-Purpose Input and Output Port 4.6/Serial Port Mux Pin 10.
14
P4.7/SPM11
I/O
General-Purpose Input and Output Port 4.7/Serial Port Mux Pin 11.
15
P0.0/BM/CMPOUT
I/O
General-Purpose Input and Output Port 0.0/Boot Mode. The ADuC7128 enters download
mode if BM is low at reset and executes code if BM is pulled high at reset through a 1 kΩ
resistor/voltage comparator output.
16
P0.6/T1/MRST
O
General-Purpose Output Port 0.6/Timer1 Input/Power-On Reset Output.
17
TCK
