This section presents conventions used in this document.
General Conventions
Bits within words and words within various memory spaces are generally numbered with 0 (zero) as the
least-significant bit or word. For example, the least-significant bit of a byte is bit 0, and the most-significant
bit is bit 7.
In addition, number ranges for bit fields and words are presented with the most-significant value first. Thus,
when discussing a bit field within a register, the bit number of the most-significant bit is written first, followed
by a colon (:), and then the bit number of the least-significant bit; for example, bits 7:0.
In this document, the names of the CL-PD6833 internal registers are boldface. For example, Chip Revision
and Power Control are register names. The names of bit fields are written with initial uppercase letters. For
example, Card Power On and Battery Voltage Detect are bit field names.
