14.7 Control and Status Space Register Descriptions

The control and status registers of the Tiny Programming Interface are mapped in the Control

and Status Space (CSS) of the interface. These registers are not part of the I/O register map

and are accessible via SLDCS and SSTCS instructions, only. The control and status registers

are directly involved in configuration and status monitoring of the TPI.

A summary of CSS registers is shown in Table 14-11.

14.7.1 TPIIR – Tiny Programming Interface Identification Register

• Bits 7:0 – TPIIC: Tiny Programming Interface Identification Code

These bits give the identification code for the Tiny Programming Interface. The code can be

used be the external programmer to identify the TPI. The identification code of the Tiny Pro-

gramming Interface is shown in Table 14-12..

14.7.2 TPIPCR – Tiny Programming Interface Physical Layer Control Register

• Bits 7:3 – Res: Reserved Bits

These bits are reserved and will always read zero.
