C
Data Pin/Auxiliary ADC9 Input. This is a multifunction input/output pin. Single-ended or
differential Analog Input 9. Analog input for the auxiliary ADC.
23 XTALO O External Crystal Oscillator Output Pin.
24 XTALI I External Crystal Oscillator Input Pin.
25 P0.4/IRQ0/PWM1 I/O General-Purpose Input and General-Purpose Output P0.4/External Interrupt Request 0/PWM1
Output. This is a triple function input/output pin.
26 P2.0/IRQ2/PWM0 I/O General-Purpose Input and General-Purpose Output P2.0/External Interrupt Request 2/PWM0
Output. This is a triple function input/output pin.
27 DGND S Digital Ground.
28 DVDD S Digital Supply Pin.
29 NTRST/
BM
I JTAG Reset/Boot Mode. Input pin used for debug and download only and boot mode (
BM
). The
ADuC7061 enters serial download mode if
BM
is low at reset and executes code if
BM
is pulled
high at reset through a 13 kΩ resistor.
30 TDO O JTAG Data Out. Output pin used for debug and download only.
31 TDI I JTAG Data In. Input pin used for debug and download only. Add an external pull-up resistor
(~100 kΩ) to this pin.
32 TCK I JTAG Clock. Input pin used for debug and download only. Add an external pull-up resistor
(~100 kΩ) to this pin.
