Electrical Specifications
6.3.9
The signals detailed in this sub-section use a “PCI” buffer
type except for LCP_CLK. LPC_CLK uses a “Q7” buffer.
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-
Note 1. t
