11. Local Bus State Controller (LBSC)
11.4.5
CSnPCR is a 32-bit readable/writable register that specifies the timing for the PCMCIA interface
connected to area n (CSnPCR, n = 5 or 6), the space property, and the assert/negate timing for the
OE and WE signals. Also, areas 5 and 6 in CSnPCR can be set for the first half and second half
individually. The first half of area 5 is allocated from H'1400 0000 to H'15FF FFFF, and the
second half of area 5 is allocated from H'1600 0000 to H'17FF FFFF. The first half of area 6 is
allocated from H'1800 0000 to H'19FF FFFF, and the second half of area 6 is allocated from
H'1A00 0000 to H'1BFF FFFF (these addresses are the local bus address). The pulse widths of OE
and WE assertion for the first half of area 5 and 6 are set by the IW bits in CSnWCR.
CSnPCR is initialized to H'7700 0000 by a power-on reset, but it is not initialized by a manual
reset.
