These correspond to the metal cut-holes. See chapter 7.4.3.
The VDD_IN pin can accept 2.2V to 4.8V. Typical value is 2.5V or 3.3V, but this depends on the
motherboard.
Check the CC2564C datasheet for more information.
The UART has by default the following characteristics (can be reprogrammed to up to 4Mbps)
