PGAxxxEVM-037 Pressure Sensor Signal Conditioner Evaluation Module
The pause pulse at the end of each data transmission can be either disabled or turned on with three
options for how the length of the pause pulse is determined.
The serial message, or slow channel communication can be enabled and configured. The slow channel
data will be contained in small portions as part of the STATUS frame at the beginning of each
transmission, when enabled. Short mode will send only 8 bits, while enhanced mode will allow the user to
send 12 or 16 bits depending on the
Enhanced Config Bit value (0b0 = 12 bits and 0b1 = 16 bits).
Both the fast- and slow-channel communication can be tested from the SENT interface page. Note that
when a test signal is begun, it will continuously output the test data until the SENT interface is disabled.
4.9 Memory Map Page
The Memory Map , shown in Figure 15 , allows low-level access to all available registers in the PGAxxx
device. Any changes made to the map on the left are not finalized until the user clicks either the Write
Selected or Write All buttons to the right of the grid.
The user can save a grid or load a previously saved grid. Note that only the active tab will be saved to a
file when saving a grid. The file created when saving the EEPROM tab grid is interchangeable with the file
created when saving the EEPROM settings on the
Memory Program page (see Section 4.11 ).
