Function
RESET is 1-byte command sequence serial
communication. The RESET command
establishes all of the specified default settings
in the device; however, it does not reset the
serial port itself. This sequence can be entered
without RDY being set.
NOP is a 1-byte command for use in serial
communication. The NOP command does not
affect the status of the RDY bit in the Serial
Status Register (SSR) and can be executed
independent of the RDY status.
RDS1 is a 1-byte command used to initiate a 1-
byte READ sequence by moving the contents of
the register identified by the address field
(AD00:04) of the command to the output
register. Addresses 00h–11h are valid in the
RDS1 command field AD00:04.
RDS2 is a 1-byte command which is used to
initiate a 2-byte READ sequence. This activity is
accomplished by moving the contents of the
two consecutive registers, starting with the one
identified by the address portion of the
command (AD00:AD04), to the output registers.
Only Addresses 00h–10h are valid in the RDS2
command field AD00:04.
The WRITE commands require 2 bytes to
execute. The first byte is the WRITE command
includes the Z86230 register address (AD00:04)
being written. The second byte (XXh) is the data
to be written.
RBS is 2-byte command to select the READ data
bank. The 2 LSBs of the second byte (0Xh)
select one of four banks of up to 33 bytes.
