Chip Select Module
8.1.3
CS0 is enabled after reset and is used to access boot ROM. The memory port width of CS0 is defined by
the state of QSPI_CLK/BUSW1 and QSPI_CS0/BUSW0. These two bits should be configured to define
the width of the boot ROM connected to CS0, as described in
Configuration
8.2
Each chip select is controlled through two 32-bit registers. The chip select base registers (CSBR0–CSBR7)
are used to enable the chip select and to configure the base address, port size, bus interface type, and
address space. The chip select option registers (CSOR0–CSOR7) are used to configure the address mask,
additional setup/hold, extended burst capability, wait states, and read/write access.
