Figure 9 Chip-Select Circuit Block Diagram
The following table lists allocation of chip-selects and discrete outputs on the pins of the MCU.
3.5.1 Chip-Select Registers
Pin assignment registers CSPAR0 and CSPAR1 determine functions of chip-select pins. These regis-
ters also determine port size (8- or 16-bit) for dynamic bus allocation.
A pin data register (PORTC) latches discrete output data.
Blocks of addresses are assigned to each chip-select function. Block sizes of 2 Kbytes to 1 Mbyte can
be selected by writing values to the appropriate base address register (CSBAR). Address blocks for
separate chip-select functions can overlap.
Chip-select option registers (CSORBT and CSOR[10:0]) determine timing of and conditions for asser-
tion of chip-select signals. Eight parameters, including operating mode, access size, synchronization,
and wait state insertion can be specified.
Initialization code often resides in a peripheral memory device controlled by the chip-select circuits. A
set of special chip-select functions and registers (CSORBT, CSBARBT) is provided to support bootstrap
operation.
