Registers

Register Conventions

This section lists the registers of the automotive CY8C21x34

PSoC device. For detailed register information, reference the

PSoC Technical Reference Manual.

The register conventions specific to this section are listed in

Table 4.

Register Mapping Tables

The PSoC device has a total register address space of 512

bytes. The register space is referred to as I/O space and is

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

determines which bank the user is currently in. When the XIO 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.
