The output data that is assigned is output to the output area as shown below.
Output data that exceeds the size (e.g., 256 bytes) that is set for the output data size parameter is separated
over more than one cycle.
To ensure that no data is lost when receiving data that is divided and output over several cycles, use the
handshake function.
Data Output Control with Handshaking: p.30
*1: At the first data output, a GATE (Data Output Completion) signal is output.
*2: If the size of the specified output data exceeds the set value of the output data size setting, the data is output separately as shown below.

timing with handshaking to
get the data.
Zeros are written to
unused bytes.
