5.9.1.1 Chip-Select Pin Assignment Registers
5-64
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[10:0] and CSBARBT). However, because the logic state of ADDR20 is al-
ways the same as the state of ADDR19 in the MCU, the largest usable block size is
512 Kbytes. Multiple chip-selects assigned to the same block of addresses must have
the same number of wait states.
Chip-select option registers (CSORBT and CSOR[0:10]) determine timing of and con-
ditions for assertion of chip-select signals. Eight parameters, including operating
mode, access size, synchronization, and wait state insertion can be specified.
Initialization software usually resides in a peripheral memory device controlled by the
chip-select circuits. A set of special chip-select functions and registers (CSORBT and
CSBARBT) is provided to support bootstrap operation.
Comprehensive address maps and register diagrams are provided in
REGISTER
The pin assignment registers contain twelve 2-bit fields that determine the functions of
the chip-select pins. Each pin has two or three possible functions, as shown in
5-22.
Table 5-23
function must not use the %00 encoding as this will cause the alternate function to be
selected. For instance, %00 for CS0/BR will cause the pin to perform the BR function.
