Section 13 Bus State Controller (BSC)
13.2.9 PCMCIA Control Register (PCR)
The PCMCIA control register (PCR) is a 16-bit readable/writable register that specifies the OE
and WE signal assertion/negation timing for the PCMCIA interface connected to areas 5 and 6.
The OE and WE signal assertion width is set by the wait control bits in the WCR2 register. For
details of access to PCMCIA, see section 13.3.7, PCMCIA Interface.
PCR is initialized to H'0000 by a power-on reset, but is not initialized by a manual reset or in
standby mode.

Bits 15 and 14—PCMCIA Wait (A5PCW1, A5PCW0): These bits specify the number of waits
to be added to the number of waits specified by WCR2 in a low-speed PCMCIA wait cycle. The
setting of these bits is selected when the PCMCIA interface access TC bit is cleared to 0.
