Double Buffer Major States
2.12 Single Buffer Operation
start
Double buffer operation may be terminated by disabling the next buffer to which the
FGPI will switch to. This is done by clearing the associated
FGPI_CTL.CAPTURE_ENABLE_n bit.
Single buffer operation may be enabled by only setting the
FGPI_CTL.CAPTURE_ENABLE_1 bit. When buffer 1 is full, sample capture will stop
until the BUF1FULL_ACK is received.
