CY8CMBR3116 how to generate Hex file to store custom information.

[NaMo_1534561]

Hi,

CY8CMBR3xxx Registers has three registers.
Configuration Registers: 0x00-0x7E
Command Registers: 0x80-0x87
Status Registers: 0x88-0xFB

What range is included in the Hex file generated by EZ-Click?

For example, what if the user wants to generate a Hex file with the value written to 0x92: DEVICE_REV?

MPN: CY8CMBR3116

Hi @NaMo_1534561,

MBR3 has the following three types of registers:

The hex file contains the data of configuration registers.

The values of the status registers cannot be modified as they are read-only registers. Only the configuration and command registers may be modified by the host (us). In the example mentioned by you, 0x92 belongs to the status registers group, and hence cannot be modified by the host.

The values of the command registers can be modified during real-time operation. To change the contents of configuration and command registers, refer to 5.2 Configuring CY8CMBR3xxx of AN90071 - CY8CMBR3xxx CapSense® Design Guide.
