Pin Function
8 or 16-bit bus mode select during power-up / reset:
NC or Pull-up (default ) = 16-bit bus
Pull-down = 8-bit bus
This pin value is also latched into register CCR, bit 6/7.
EEPROM select during power-up / reset:
Pull-up = EEPROM present
NC or Pull-down (default ) = EEPROM not present
This pin value is latched into register CCR, bit 9.
Endian mode select during power-up / reset:
Pull-up = Big Endian
NC or Pull-down (default) = Little Endian
This pin value is latched into register CCR, bit 10.
When this pin is no connect or tied to GND, the bit 11 (Endian mode selection) in RXFDPR
register can be used to program either Little (bit11=0 default) Endian mode or Big (bit11=1)
Endian mode.
Note: IPU/O = Input with internal pull-up (58K ±30%) during power-up/reset; output pin otherwise.
IPD/O = Input with internal pull-down (58K ±30%) during power-up/reset; output pin otherwise.
Pin strap-ins are latched during power-up or reset.
