The signals detailed in this sub-section use a “Q7” 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-
Note 1. t
Note 2. Signals are referenced to AC_CLK high-to-low edge.
Note 3. For AC_S_IN2, GPIO12 configured: (Aux In) and Input Enable = 1; Output Enable, AUX_OUT_1, and AUX_OUT_2
Note 4. Signal is referenced to LPC_CLK low-to-high edge.
Note 5. For AC_BEEP, GPIO1 configured: AUX_OUT_1 and Output Enable = 1; Open-drain, AUX_OUT_2, and Input En-
