Chip Select Decode
Value on reset: 0
Variants
0: The chip selects are directly connected to a peripheral device.
1: The four chip select lines are connected to a 4- to 16-bit decoder.When PCSDEC equals one, up to 15 Chip Select signals can be generated with the four lines using an external 4- to 16-bitdecoder. The Chip Select Registers define the characteristics of the 16 chip selects according to the following rules:CSR0 defines peripheral chip select signals 0 to 3.CSR1 defines peripheral chip select signals 4 to 7.CSR2 defines peripheral chip select signals 8 to 11.CSR3 defines peripheral chip select signals 12 to 15.
