Text Conventions
This document uses the following text conventions:
• The default radix is decimal.
– Hexadecimal constants are suffixed with a subscript letter ‘H’, as in: FFC
H
.
– Binary constants are suffixed with a subscript letter ‘B’, as in: 111
B
• Register reset values are not generally architecturally defined, but require setting on startup in a given
implementation of the architecture. Only those reset values that are architecturally defined are shown in this
document. Where no value is shown, the reset value is not defined. Refer to the documentation for a specific
TriCore implementation.
• Bit field and bits in registers are in general referenced as ‘Register name.Bit field’, for example PSW.IS. The
Interrupt Stack Control bit of the PSW register.
• Units are abbreviated as follows:
– MHz = Megahertz.
– kBaud, kBit = 1000 characters/bits per second.
– MBaud, MBit = 1,000,000 characters per second.
– KByte = 1024 bytes.
– MByte = 1048576 bytes of memory.
– GByte = 1,024 megabytes.
• Data format quantities referenced are as follows:
– Byte = 8-bit quantity.
– Half-word = 16-bit quantity.
– Word = 32-bit quantity.
– Double-word = 64-bit quantity.
• Pins using negative logic are indicated by an overbar: BRKOUT.
In tables where register bit fields are defined, the conventions shown in the following table are used in this
document.
Table 0-1 Bit Type Abbreviations
Abbreviation Description
r Read-only. The bit or bit field can only be read.
w Write-Only. The bit or bit field can only be written.
rw The bit or bit field can be read and written.
h The bit or bit field can be modified by hardware (such as a status bit). ‘h’ can be combined
with ‘rw’ or ‘r’ bits, to form ‘rwh’ or ‘rh’ bits.
- Reserved. Read value is undefined, but must be written with 0.
