DESCRIPTION
NAME NO.
PCI
Notes: When PCI boot mode is not used, for proper device operation out of reset PCIEN must be "0".
The PCI pin functions are enabled when PCIEN = 1 (PCI mode). This can be done via an external PU on the PCIEN pin (AC6) or by setting
the PCIEN bit (bit 2) in the PINMUX0 register to a "1" after device reset. For more details on the PCIEN pin, see Table 3-5, Boot Terminal
Functions.
In PCI mode (PCIEN = 1), the internal pullups/pulldowns (IPUs/IPDs) are disabled on all PCI pins and it is recommended to have external
pullup resistors on the PCI_RSV[5:0] pins. For more detailed information on external pullup/pulldown resistors, see Section 4.8.1,
Pullup/Pulldown Resistors.
Also in PCI mode (PCIEN = 1), the internal pulldowns (IPDs) are disabled on the GP[5:7] pins. It is recommended to have external pullup
resistors on the GP[5] pin when PCIEN = 1 and on GP[6:7] pins when PCIEN = 1 and VADJEN = 0.
