Control and Status Space Register Descriptions
ATtiny4/5/9/10
TPIIR – Tiny Programming Interface Identification Register
TPIPCR – Tiny Programming Interface Physical Layer Control Register
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. Summary of Control and Status Registers
• 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. Identification Code for Tiny Programming Interface
• Bits 7:3 – Res: Reserved Bits
These bits are reserved and will always read zero.
