TRF7970A EVM Description
Figure 1. TRF7970A EVM (Top Side)
If a logic analyzer is to be connected to the TRF7970A EVM, the user can install three-position 2-mm
board headers at positions HDR_1 and HDR_3 for observation of DATA_CLK and IRQ signals. An
8-position 2-mm board header can be installed at position HDR_5 for observation of the parallel or SPI
signals between the MSP430F2370 and the TRF7970A. See the PCBA silkscreen or Table 1 and Table 2
for reference.
