Pin Multiplexing

Multifunction Pin Multiplexing in the MEC1632 is controlled by the GPIO Interface and illustrated in the Multiplexing

Tables that follow. See Section 3.7, "Notes for Tables in this Chapter," on page 53 for notes that are referenced in the

Pin Multiplexing tables. See Section 24.9.1, "Pin Control Register," on page 396 for pin multiplexing programming

details. See also Section 24.7, "Pin Multiplexing Control," on page 391.

Pin signal functions that exhibit power domain emulation have a different power supply designation in the “Emulated

Power Well” column and “Signal Power Well“ columns of the multiplexing tables in Section 3.6.2. See also Section

3.4.1, "Pin Default State Through Power Transitions," on page 15 for a description of pin states through power transi-

tions.

Several signals that are alternate functions for GPIOs are not selected using the GPIO mux controls. These signals

include the Gang Programmer interface. These signals are not listed in the following tables.

3.6.1

VCC POWER DOMAIN EMULATION

Pin signal functions that exhibit VCC Power Domain Emulation are documented in the multiplexing tables as “Signal

Power Well“= VTR and “Emulated Power Well” = VCC. The System Runtime Supply power VCC is not connected to

the MEC1632. The VCC_PWRGD signal is used to indicate when power is applied to the System Runtime Supply. All

pin signal functions that exhibit VCC power domain emulation are powered by VTR and controlled by the VCC_PWRGD

signal input. Outputs on VCC power domain emulation pin signal functions are tri-stated when VCC_PWRGD is not

asserted and are functional when VCC_PWRGD is active. Inputs on VCC power domain emulation pin signal functions

are gated according as defined by the Gated State column in the following tables.

3.6.2

MULTIPLEXING TABLES

In the following tables, the columns have the following meanings:

3.6.2.1

Pin Ref. Number

Every pin has a reference number. The mapping between pin reference numbers and signal names is summarized in

the first table in this chapter.
