General Conventions
The following general conventions apply to this document.
Bits within words and words within various memory spaces are generally numbered with a 0 (zero)
as the least-significant bit or word. For example, the least-significant bit of a byte is bit 0, while 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 hyphen (-) and then the bit number of the least-significant bit; as in,
bits 7-0.
In this document, the names of the PD6729 internal registers are bold-faced. For example, Chip
Revision and Power Control are register names. The names of bit fields are written with initial
upper-case letters. For example, Card Power On and Battery Voltage Detect are bit field names.
Numbers and Units
10
20
The unit Kbyte designates 1024 bytes (2
). The unit Mbyte designates 1,048,576 bytes (2
). The
30
unit Gbyte designates 1,073,741,824 bytes (2
). The unit Hz designates hertz. The unit kHz
designates 1000 hertz. The unit MHz designates 1,000,000 Hz. The unit ms designates millisecond.
The unit s designates microsecond. The unit ns designates nanosecond. The unit mA designates
milliampere. The unit V immediately following a number designates volt.
Hexadecimal numbers are presented with all letters in uppercase and a lowercase h appended. For
example, 14h and 03CAh are hexadecimal numbers.
Binary numbers have the letter b appended to them or are enclosed in single quotation marks. For
example, 11b and ‘11’ are binary numbers.
Numbers not indicated by an h or b are decimal.
In addition, a capital letter X is used within numbers to indicate digits ignored by the PD6729
within the current context. For example, 101XX01b is a binary number with bits 3-2 ignored.
