Hi,
I have interfaced TRF7960 with a Renesas Microcontroller (R8C/2C). When the TRF7960 chip is enabled i am getting a 3.4 MHz frequency at SYS_CLK pin.
The communication between TRF chip and mcu is through SPI with SS (Slave Select). I am able to read the default values of all registers, but not able to change those values. Reading the registers after performing write with non default values still give default values. The change in clock phase during the shift from write to read cycles is taken care according to the TRF data sheet.
MCU Clock - 20 MHz, SPI Data Clock - 300 KHz
Please provide the information or steps to be taken to get write into registers working.
Regards,
Ashwin
