3.2.2 8-Bit Expanded Mode
In 8-bit expanded mode (BERR = 1, DATA1 = 1), pins DATA[7:0] are configured as an 8-bit I/O port.
Pins DATA[15:8] are configured as data pins. Pins ADDR[18:3] are configured as address pins. Emu-
lator mode is always disabled.
1. These pins have only one reset configuration in 8-bit expanded mode.
