6.11 Breakout Headers and Jumpers

The SmartRF06EB has several breakout headers, giving access to all EM connector pins. An

overview of the SmartRF06EB I/O breakout headers is given in Figure 16. Probe headers P406,

P407, P411 and P412 give access to the I/O signals of the mounted EM. Breakout headers P403,

P404 and P405 allow the user to map any EM I/O signal to any peripheral on the SmartRF06EB.

The XDS bypass header (P408) makes it possible to disconnect the XDS100v3 Emulator

onboard the EB from the EM. Using the 20-pin ARM JTAG header (P409) or the 10-pin ARM

Cortex Debug Header (P410), it is possible to debug external targets using the onboard emulator.

I/O Breakout Headers

The I/O breakout headers on SmartRF06EB consist of pin connectors P406, P407, P411 and

P412. P406, P407 and P411 are located at the top left side of SmartRF06EB. All EM signals

available on these probe headers can be connected to or disconnected from SmartRF06EB

peripherals using jumpers on headers P403, P404, P405.

Probe header P412 is located near the bottom right corner of the SmartRF06EB. The signals

available on P412 are connected to the XDS100v3

Emulator’s UART back channel using jumpers

on header P408.

The I/O breakout mapping between the SmartRF06EB and the mounted EM is given in Table 14.

The leftmost column in the below table refers to the silk print seen on the SmartRF06EB. The

rightmost column shows the corresponding CC2538 I/O pad on CC2538EM.

NOTE: By default, all jumpers are mounted on P403, P404, P405 and P408. The default

configuration is assumed in this user’s guide unless otherwise stated.
