RESET:
RESET:
Reset clears PCSEN in single-chip modes and sets PCSEN in expanded modes.
These bits determine the starting address of the CSGEN valid address space and correspond to the
high-order address bits ADDR[15:10]. Table 19 illustrates how the block size selected determines
which of this register's bits are valid.
0 = CSPROG disabled
1 = CSPROG enabled
0 = CSIO1 is valid during E-clock valid time (E-clock high)
1 = CSIO1 is valid during address valid time
0 = CSIO2 is valid during E-clock valid time (E-clock high)
1 = CSIO2 is valid during address valid time
