modes using the FIFO: modes 01, 10, 11 timing (continued)
Mode 10 (sweep mode) requires reconfiguration at the start of each new sweep sequence. Once the FIFO is
filled up to the programmed threshold, the host has the option to either read the FIFO or configure for other
modes. Once the FIFO is read, the host must reconfigure the device before the next sweep sequence can be
started. So the sequence is either configure : triggered conversions : FIFO read : configure. or configure :
triggered conversions : configure : .... Each configure clears the FIFO and the action that follows the configure
command depends on the mode setting of the device.
Mode 11 (repeat sweep mode) requires one cycle configuration. This sweep sequence can be repeated without
reconfiguration. Once the FIFO is filled up to the programmed threshold, the host has the option to either read
the FIFO or configure for other modes. So the sequence is either configure : triggered conversions : FIFO read
: triggered conversions : FIFO read ... or configure : triggered conversions : configure : .... Each configure clears
the FIFO and the action that follows the configure command depends on the mode setting of the device.
