Hello,
In TMS320C6A816x Technical Reference Manual, p449(3.2.15.4 EMAC Module Initialization).
1. Program the VDD3P3V_PWDN register in the System module to power up the CPGMAC I/O cells
(see the device-specific data manual). There are separate controls for MII I/O pins and GMII I/O
pins, which are powered down by default at system reset, to save power.
Currently, I can't find the mannual in TI website, where can I get the *device-specific data manual*
which has the detail description of VDD3P3V_PWDN register? Many thanks!
Best Regards,
Gary
