Chapter 2

User pushbuttons,

S6 and S7 Use the user pushbuttons to interact with the applications running on the NS9210

Processor Module. Use these module signals to implement the pushbuttons:

Legend for multi-

pin switches Switches 1 and 4 are multi-pin switches. In the description tables for these switches,

the pin is designated as S[switch number].[pin number]. For example, pin 1 in switch

4 is specified as S4.1.

configuration

switches, S4

Use S4 to configure the module:

Wake-up button,

S8 The wake-up pushbutton, S8, generates an external interrupt to the module's NS9215 processor using the EIRQ2

signal.

Signal name Switch

(pushbutton) GPIO used

USER_PUSH_BUTTON_1 S6 GPIO81

USER_PUSH_BUTTON_2 S7 GPIO84

Switch pin Function

S4.1 On = Little endian

Off = Big endian

S4.2 Not used

S4.3 On = ARM Debug

Off = Boundary Scan

S4.4 Not used

S4.5 – S4.8 Not defined. Software configuration signals, which can be available for user

specific configuration.
