MANUAL CONVENTIONS
The following conventions are used in this manual:
• Bits within registers are always listed from Most Significant Bit (MSB) to Least
Significant Bit (LSB).
• Bits within a register are indicated AA[n:m], n>m, when more than one bit is
involved in a description. For purposes of description, the bits are presented as if
they are contiguous within a register. However, this is not always the case. Refer
to the programming model diagrams or to the programmer’s sheets to see the
exact location of bits within a register.
• When a bit is described as “set,” its value is 1. When a bit is described as
“cleared,” its value is 0.
• The word “assert” means that a high true (active high) signal is pulled high to
V
CC
or that a low true (active low) signal is pulled low to ground. The word
“deassert” means that a high true signal is pulled low to ground or that a low true
signal is pulled high to V
CC
. See Table 1-1.
• Pins or signals that are asserted low (made active when pulled to ground)
– In text, have an overbar: for example, RESET is asserted low.
– In code examples, have a tilde in front of their names. In the example on the
following page, line 3 refers to the SS0 pin (shown as
~SS0
).
• Sets of pins or signals are indicated by the first and last pins or signals in the set,
for instance HA1–HA8.

Note:
1.
PIN is a generic term for any pin on the chip.
2.
Ground is an acceptable low voltage level. See the appropriate data sheet
for the range of acceptable low voltage levels (typically a TTL logic low).
3.
V
CC
is an acceptable high voltage level. See the appropriate data sheet for
the range of acceptable high voltage levels (typically a TTL logic high).
