11.4.5 CSn PCMCIA Control Register (CSnPCR)
CSnPCR is a 32-bit readable/writable register that specifies the timing for the PCMCIA interface
connected to area n (n = 5 and 6), the space property, and the assert/negate timing for the
OE
and
WE
signals. The pulse widths of
OE
and
WE
are set using the wait control bits in CSnWCR.
CSnPCR is initialized to H'7700 0000 by a power-on reset or a manual reset.
