VII.3.2 Status output
The operation information, such as internal status, play time information, folder information, file information, ID3Tag
information, AACTag information and WMATag information, is output using an I
Statuses as shown in Table VII.3.2.1 MODE 2 Status Register Map are output.
The status register has a ring buffer structure of OFFSET 0x00-0x7F. The OFFSET position is automatically
incremented after reading byte data.
Status read specifies OFFSET of the status register map. There are two methods available: to read a desired
number of bytes continuously from the OFFSET position and to read the data by one command without specifying the
OFFSET position. Figure VII.3.2.2 shows the status output commands. Table VII.3.2.3 shows the enabled/disabled
state of the status output commands.
Status register outputs a byte data of OFFSET 0x00-0x7F by "Little Endian" format. (Except for WMA tag reading)
