010000H using the CS0 areas.
upper 8 bits of the start address). Next, calculate the difference between the start
address and the anticipated end address (01FFFFH) based on the size of the CS0 area.
Bits 20 to 8 of the result correspond to the mask value to be set for the CS0 area.
Setting this value in memory address mask register MAMR0<V20:8> sets the area size.
This example sets 07H in MAMR0 to specify a 64K-byte area.
B0CS<B0E>, B1CS<B1E> and B3CS<B3E> are reset to 0. This disabling the CS0, CS1
and CS3 areas. However, as B2CS<B2M> to 0 and B2CS<B2E> to 1, CS2 is enabled
from 000FE0H to 000FFFH and 003000H to FFFFFFH in TMP91C820A. Also, the bus
width and number of waits specified in BEXCS are used for accessing addresses
outside the specified CS0 to CS3 area. (See 3.6.2 “Chip Select/Wait Control Registers”.)
