Register Reference

This section lists the registers of the CY8C23433 PSoC device

by using mapping tables, in offset order.

Register Conventions

Abbreviations Used

The register conventions specific to this section are listed in the

following table.

Register Mapping Tables

The PSoC device has a total register address space of 512

bytes. The register space is referred to as IO space and is

divided into two banks. The XOI bit in the Flag register (CPU_F)

determines which bank the user is currently in. When the XOI bit

is set the user is in Bank 1.

Note In the following register mapping tables, blank fields are

reserved and must not be accessed.
