NUMBER NOTATIONS

Notation Description

bit N Bits are numbered in little endian format, that is, the least

significant bit of a number is referred to as Bit 0

V[X:Y] Bit field representation covering bit X to Y of a value or a field V

0xNN Hexadecimal (base-16) numbers are preceded by the prefix‘0x’

0bNN Binary (base-2) numbers are preceded by the prefix ‘0b’

NN Decimal (base-10) are represented using no additional prefixes

or suffixes

Mode Description

R/W Memory location has read and write access.

R Memory location has read access only. A read always returns 0

unless specified otherwise.

W Memory location has write access only.
