DESCRIPTION
By default, no function is enabled upon reset.
VP0EN bit = 0 (disabled)
MCASP0EN bit = 0
(disabled)
To enable the Video Port 0 data pins, the VP0EN bit in the
PERCFG register must be set to a 1. (McASP0 control
pins are disabled).
To enable the McASP0 control pins, the MCASP0EN bit in
the PERCFG register must be set to a 1. (VP0 upper data
pins are disabled).
VP0EN bit = 0 (disabled)
MCBSP0EN bit = 1
(enabled)
By default, the McBSP0 peripheral function is enabled
upon reset (MCBSP0EN bit = 1).
To enable the Video Port 0 data pins, the VP0EN bit in the
PERCFG register must be set to a 1.
By default, no functions enabled upon reset (PCI is
disabled).

(disabled) ⁽²⁾
To enable the PCI peripheral, an external pullup resistor
(1 kΩ) must be provided on the PCI_EN pin (setting
PCI_EN = 1 at reset)
To enable the MDIO peripheral (which also enables the
EMAC peripheral), an external pullup resistor (1 kΩ) must
be provided on the MAC_EN pin (setting MAC_EN = 1 at
reset)
