start
OUTPUT_ENABLE_2. Buffer 1 will become the active buffer first. Starting with the
next record or message start event samples will be output from buffer 1 until either
output is disabled or buffer 1 is terminated by a buffer start event.
Double buffer operation may be terminated by disabling the next buffer to which the
FGPO will switch to. This is done by clearing the associated
FGPO_CTL.OUTPUT_ENABLE_n bit.
Single buffer operation may be enabled by only setting the
FGPO_CTL.OUTPUT_ENABLE_1 bit. When buffer 1 is done, sample output will stop
until the BUF1DONE_ACK is received.
Initialize all registers except the FGPO_CTL register, first, then load the FGPO_CTL
register with the OUTPUT_ENABLE_1 and OUTPUT_ENABLE_2 bits set.
