IDE Signals in Flash Mode

The signals detailed in this sub-section use an “IDE” buffer

type. For a detailed explanation of buffer types, see Table

2-4 "Buffer Type Characteristics" on page 28.

In this subsection, unless otherwise noted:

• All timing specifications are specified under the oper-

ating conditions listed in Table 6-3 on page 526 (i.e.,

VCORE and VCORE_VSB = All; VIO and VIO_VSB = All;

TCASE = All).

• Signals are referenced to LPC_CLK.

• Signal parameters are defined in Figure 6-2 "AC Refer-

ence Timing and Test Definition" on page 530.
