Data Transfer Acknowledge Output.
Ready Output.
Serial Data Output.
In Motorola Mode a Low signal during a databus read operation indicates that
the information is valid. A Low signal during a write operation acknowledges
that a data transfer into the addressed register has been accepted
(acknowledge signal). In Motorola Mode wait states only occur if a write cycle
immediately follows a previous read or write cycle (e.g. read modify write). In
Intel mode a High signal acknowledges that a register access operation has
been completed (Ready Signal). A Low signal on this pin signals that a data
transfer operation is in progress. The pin goes tristate after completion of a
bus cycle.
In Serial Host mode, if CLKE is High, SDO is valid on the rising edge of
SCLK. If SCLKE is Low, SDO is valid on the falling edge of SCLK. This pin
goes into high Z state during a serial port write access.
Data Strobe Input.
Write Enable Input.
Serial Data Input.
This pin acts as data strobe in Motorola mode and as Write Enable in Intel
mode. In serial mode, this pin is used as Serial Data Input.
Read/Write Input.
Read Enable Input.
This pin functions as the read/write signal in Motorola mode and as the Read
Enable in Intel mode.
Address Latch Enable Input.
Shift Clock Input.
Address Strobe
The address on the multiplexed address/data bus is clocked into the device
with the falling edge of ALE.
In serial Host mode, this pin acts as serial shift clock.
In Motorola mode, this pin acts a an active Low address strobe.
Chip Select Input.
This active Low input is used to access the serial/parallel interface. For each
read or write operation, CS must transition from High to Low and remain Low.
Motorola/Intel Select Input. When low, the host interface is configured for
Motorola microcontrollers. When High, the host interface is configured for
Intel microcontrollers.
