CyClocksRT Reserved Bits of CY22393

Last Updated: September 13, 2011

When using Bitviewer in CyClocks to check for programming accuracy, the Reserved Fields at address 18H - 1BH are set to values other than 0. Specifically, when setting the Activate Suspend Mode, bits are set. What are the functions of these reserved fields and how they should be set?


The registers, 18H - 1BH, need not be set when serially shifting the configuration bits. When using suspend mode, the value for those registers can be found in BitViewer. These registers are used for the device ID suspend mode and I2C, but specific functionality is proprietary.
