system is installed, the calibrator would be used to
control calibration and/or to program user-speci-

PROM. The commands/data will determine the

initialization sequence is running. Any of the valid

3.3.2 Auto-boot Data for EEPROM
This section illustrates what a typical set of code
would look like for an auto-boot sequence. This
code is what would be written into the EEPROM. In
the sequence below, the EEPROM is programmed
so that it will first send out commands that write cal-
ibration values to the calibration registers inside
the CS5460A. This is followed by the commands
used to set (write) the desired Pulse-Rate Register
value, and also to un-mask the ‘LSD’ status bit in
the Mask Register. Finally, the EEPROM code will
initiate ‘continuous computation cycles’ data acqui-
sition mode and select one of the alternate
pulse-output formats (e.g., set the MECH bit in the
Control Register). The serial data for such a se-
quence is shown below in single-byte hexidecimal
notation:
computation cycles.
78 00 01 40 ;Write STOP bit to Control
Register, to terminate au-
to-boot initialization se-
quence, and also set the
EOUT pulse output to Me-
chanical Counter Format.
This data from the EEPROM will drive the SDI pin
of the CS5460A during the auto-boot sequence.
The following sequence of events will cause the
CS5460A to execute the auto-boot mode initializa-
tion sequence: (A simple timing diagram for this se-
quence is shown below in Figure 14.) If the MODE
pin is set to logic high (or if the MODE pin was
set/tied to logic high during/after the CS5460A has
been powered on), then changing the RESET pin
from active state to inactive state (low to high) will
cause the CS5460A to drive the CS pin low, and af-

command on the CS5460A’s SDO line. Once these
events have completed, the CS5460A will continue
to issue SCLK pulses, to accept data/commands
from the EEPROM. The serial port will become a
master -mode interface. For a more detailed timing
diagram, see Switching Characteristics (in Section
1 .)
