Chip Select x Bus Mode Control Register+The Chip Select Bus Mode register,
listed in
modes. Changing the bus mode allows the eZ80F92 device to interface to peripherals
based on the Z80-, Intel-, or Motorola-style asynchronous bus interfaces. When a bus
mode other than CPU is programmed for a particular Chip Select, the CSx_WAIT setting
in that Chip Select Control Register is ignored.
