#15 Added pull-up resistor for "HOLD"-function (R92, R100) and "WP"-function (R93, R102) for flash (U7, U17).
Type: Schematic Change
Reason: Improved SPI interface usage with different flashs.
Impact: None.
#16 Added pull-up resistor
...
Type: Schematic Change
Reason: Improved SPI interface usage with different flashs.
Impact: None.
...
(R107) (default: not fitted) and pull-down resistor (R109) (default: fitted) for signal "POR_OVERRIDE" (U1).
Type: Schematic Change
Reason: Enable POR Override Add option to enable POR_OVERRIDE feature.
Impact: None.
