D[0..15]
The default configuration for the Static Memory Controller, byte select mode, 16-bit data bus,
Read/Write controlled by Chip Select, allows access on 16-bit non-volatile memory at slow
clock.
For another configuration, configure the Static Memory Controller CS0 Setup, Pulse, Cycle and
Mode depending on Flash timings and system bus frequency.
• Address lines A[1..22], NCS0, NRD, NWE and data lines D[8..15] are multiplexed with PIO
lines and thus dedicated PIOs must be programmed in peripheral mode in the PIO controller.
