SECTION 5
SIGNAL DESCRIPTION
This section contains brief descriptions of the input and output signals in their functional
groups (see Figure 5-1). Each signal’s function is briefly explained, referencing other
sections that contain detailed information about the signal and related operations. Table
5-1 lists the signal names, mnemonics, and functional descriptions of the input and output
signals for the M68040. Timing specifications for these signals can be found in Section 11
MC68040 Electrical and Thermal Characteristics.
MOTOROLA
Assertion and negation are used to specify forcing a signal to a
particular state. Assertion and assert refer to a signal that is
active or true. Negation and negate refer to a signal that is
inactive or false. These terms are used independent of the
voltage level (high or low) that they represent.
For the MC68040V, MC68LC040, MC68EC040, and
MC68EC040V ignore all references to the floating-point unit
(FPU). For the MC68EC040 and MC68EC040V only, ignore all
references to the memory management unit (MMU). Some pin
names are different on these parts; please refer to the
appropriate appendix in the back of this book for more
information.
