Miscellaneous Conventions
Register Documentation Conventions
Register diagrams use the following conventions:
• The descriptive name of the register appears at the top with the short form of the name.
• If a bit has a short name, the short name appears first in the bit description, followed by the long name.
• The reset value appears in binary in the individual bits and in hexadecimal to the left of the register.
• Bits marked X have an unknown reset value. Consequently, the reset value of registers that contain such bits is
undefined or dependent on pin values at reset.
• Shaded bits are reserved
To ensure upward compatibility with future implementations, write back the value that is read for reserved
NOTE:
bits in a register, unless otherwise specified.
Register description tables use the following conventions:
• Each bit's or bit field's access type appears beneath the bit number in the table in the form (read-access/write-
access). The access types include:
• R = read, RC = read clear, RS = read set, R0 = read zero, R1 = read one, Rx = read undefined
• W = write, NW = no write, W1C = write one to clear, W1S = write one to set, W0C = write zero to clear,
W0S = write zero to set, WS = write to set, WC = write to clear, W1A = write one action

A caution identifies conditions or inappropriate usage of the product that could
lead to undesirable results or product damage. In the online version of this book,
the word CAUTION: appears instead of this symbol.

All registers and bits in this manual are linked (clickable) to their respective de-
scriptions in the "Register Descriptions" of each chapter.
Interrupt and internal signals are shown in all caps with no other formatting. For
example the SPDIFn_RX or SCLK signal or the PKTE0_IRQ interrupt.
An overbar denotes an active-low signal as in SYS_FAULT.
