A full view of registers in RAM can be found in the device-specific Technical Reference Manual and also in the Data Memory screen of BQStudio. To enable viewing the RAM register addresses in BQStudio, go to the Window->Preferences menu and select 'Show Advanced Views'. Reading from a RAM register is accomplished by writing the register address to 0x3E and then reading from the data buffer starting at 0x40. Writing to a RAM register starts with writing the register address to 0x3E followed by the data, followed by a write to 0x60/0x61 with the checksum and length. The checksum and length calculation is described more in the device-specific data sheet, but is illustrated in the following examples.
