DEVICE CONFIGURATIONS (CONTINUED)
multiplexed pins
Multiplexed pins are pins that are shared by more than one peripheral and are internally multiplexed. Some of
these pins are configured by software, and the others are configured by external pullup/pulldown resistors only
at reset. Those MUXed pins that are configured by software can be programmed to switch functionalities at any
time. Those MUXed pins that are configured by external pullup/pulldown resistors are mutually exclusive; only
one peripheral has primary control of the function of these pins after reset. Table 29 identifies the multiplexed
pins on the C6414, C6415, and C6416 devices; shows the default (primary) function and the default settings
after reset; and describes the pins, registers, etc. necessary to configure specific multiplexed functions.
debugging considerations
It is recommended that external connections be provided to device configuration pins, including
CLKMODE[1:0], BEA[20:13, 11, 9:7], HD5/AD5, PCI_EN, and MCBSP2_EN. Although internal pullup/pulldown
resistors exist on these pins (except for HD5/AD5), providing external connectivity adds convenience to the user
in debugging and flexibility in switching operating modes.
Internal pullup/pulldown resistors also exist on the non-configuration pins on the BEA bus (BEA[12, 10, 6:1]).
Do not oppose the internal pullup/pulldown resistors on these non-configuration pins with external
pullup/pulldown resistors. If an external controller provides signals to these non-configuration pins, these
signals must be driven to the default state of the pins at reset, or not be driven at all.
For the internal pullup/pulldown resistors on the C6414, C6415, and C6416 device pins, see the terminal
functions table.
