I need TRF7960a to work on full output power at 5V, there are external CMU and TRF7960A on my board, also there are 3.3V for external CMU and 5V power supply for TRF7960A, internal power VDD_X(3.4V) of TRF7960A only supplies VDD_IO of TRF7960A. CMU controls TRF7960A via SPI bus, there is not good signal level match between CMU IO(3.3V) and TRF7960 IO(3.4V); additionally 2 registers for Manual 5V system is wrote as below:
1. Chip Status Control Register (0x00): B4=0; B0=1;
2. Regulator and I/O Control Register (0x0B): B7=0; B2=1;B1=1;B0=1.
Can it work well based on above hardware and register set?
Thanks.
