Description
16/68 Interface type select (input with internal pull-up). This input provides
the 16 (Intel) or 68 (Motorola) bus interface type select. The functions of IOR,
IOW, INTA-INTD, and CSA-CSD are re-assigned with the logical state of this
pin. When this pin is a logic 1, the 16 mode interface (16C654) is selected.
When this pin is a logic 0, the 68 mode interface (68C654) is selected. When
this pin is a logic 0, IOW is re-assigned to R/W, RESET is re-assigned to
RESET, IOR is not used, and INTA-INTD are connected in a wire-OR
configuration. The wire-OR outputs are connected internally to the open drain
IRQ signal output. This pin is not available on 64-pin packages which operate in
the 16 mode only.
Address 0 select bit. Internal registers address selection in 16 and 68 modes.
Address 1 select bit. Internal registers address selection in 16 and 68 modes.
Address 2 select bit. Internal registers address selection in 16 and 68 modes.
Quad UART with 64-byte FIFO and infrared (IrDA) encoder/decoder
