The BSC has four registers. For details on these register addresses and register states in each
processing states, refer to appendix A, Internal I/O Register.
These registers are used to control wait states, bus width, and interfaces with memories like ROM
and SRAM. All registers are 16 bits.
• Bus control register 1 (BCR1)
• Bus control register 2 (BCR2)
• Wait control register 1 (WCR1)
• RAM emulation register (RAMER)
