nRF24LE1 Preliminary Product Specification
The nRF24LE1 has the following on-chip hardware debug support for a JTAG debugger:
These debug modules are available on device pins OCITO, OCTMS, OCITDO,OCITDI, OCITCK when
enabled in the flash InfoPage. The HW debug features can be interfaced to a PC and utilized in the Keil
Integrated Development Environment (IDE) by running nRFProbe found in the nRFgo development kits or
dedicated HW from First Silicon Solutions.
27.1
The features listed below are for the Keil µVision debugger only:
27.2
The JTAG debug interface is enabled by writing (through the flash SPI slave interface described in
6.3.4 on page
Flash Status Register (FSR bit 7,
The GPIO allocated in debug mode for each of the package alternatives is given in
130, but summarized in
A separate "Trigger Out" is available on the OCITO pin. This output can be activated when certain address
and data combinations occur.
