8.4 I/O Primary and Secondary Address Configurations
When the system decodes the Primary and Secondary Address Configurations, the registers are accessed in the
Address A0 must be low for all word accesses. As for the Memory Mapped Addressing, register 0 is accessed with –
CE1 Low and – CE2 Low (A0 must be 0) as a Word register on the combined Odd and Even Data Bus (D15 to D0). This
register may also be accessed with – CE1 Low and – CE2 High, by a pair of Byte accesses to offset 0. The address
space of this Word register overlaps the address space of the Error and Feature Byte-wide registers at offset 1.
When accessed twice as Byte register with – CE1 Low, the first Byte is the even Byte of the Word and the second is
the odd Byte. A Byte access to register 0 with – CE1 High and – CE2 Low accesses the error (read) or feature (write)
register.
