(1)
The GPIO3 pin is also used as SOP0 bootmode configuration pin.
(2)
The GPIO4 pin is also used as SOP1 bootmode configuration pin.
(3)
GPIO135 is implemented with the I2C OD FS (Open Drain Fail Safe) voltage buffer.
(4)
GPIO134 is implemented with the I2C OD FS (Open Drain Fail Safe) voltage buffer.
(5)
The GPIO12 pin is also used as SOP2 bootmode configuration pin.
(6)
The GPIO13 pin is also used as SOP3 bootmode configuration pin.
(7)
In OSPI boot mode, the AM261x ROM code configures GPIO61 as OSPI0_RESET_OUT0 and drives the pin low to reset an external
OSPI device during this boot mode. However, due to a configuration in the OSPI controller, this pin does not de-assert after and
external OSPI flash device resets, thus holding any external flash device in reset and causing the boot to fail. This means that GPIO61
is pulled high and then configured low until after boot is completed, which may affect certain applications. For more information, see
the AM261x Errata Document.
(8)
For additional information on OSPI flash reset, see OSPI Reset within the Applications, Implementation and Layout section.
