Freescale Semiconductor
16.3.5.6
Chip Select Pin Assignment Register (PAR_CS)
The PAR_CS register controls the functions of the FlexBus chip select pins. After reset, the byte enable
signals are configured to their primary functions.
16.3.5.7
Timer Pin Assignment Registers (PAR_TIMER)
The PAR_TIMER register controls the functions of the DMA timer pins.
