4 0x60 0x07 N M ・Set up CLKOUT12 terminal and a TEST12 terminal output.
・Select N at the 3^rd byte from the following. Any other settings will not
accept the command.
N=0x00: Disables 12 MHz clock output from the CLKOUT12 terminal.
N=0x01: Enables 12 MHz clock output from the CLKOUT12 terminal.
・Select M at the 4^th byte from the following. Any other settings will not
accept the command.
M=0x00: Disables 16.9344 MHz clock output from the TEST12
terminal.
M=0x01: Enables 16.9344 MHz clock output from the TEST12 terminal.
・The 16.9344 MHz clock is a clock which buffers the input from the
XIN_PLL terminal.
・initial setting is N= 0x00 and M= 0x00. Output is invalid.
4 0x60 0x08 N M ・Set up a NATIVE language.
・Select N and M at the 3^rd and 4^th bytes from the following. Any other
setting is considered to specify {M, N}={0x00,0x00}: ASCII.
{ M, N }= { 0x03, 0xA4 }: SHIFT-JIS(CP932)
{ M, N }= { 0x03, 0x52 }: OEM_850
・Initial setting is {M , N} = {0x03, 0xA4} ; SHIFT JIS(CP932).
4 0x60 0x09 N 0x00 ・Select the layer of the MPEG audio to play.
・Select N at the 3^rd byte from the following. Any setting other than
N=0x00 is considered to specify N=0x01.
N=0x00: Plays all the files having extension mp1, mp2, and mp3.
N=0x01: Plays the files having extension mp3 only.
・Initial setting is N= 0x00. All the files of mp1, mp2, and mp3 are
reproduced.
4 0x60 0x0A N 0x00 ・Specify the number of entries (a file or folder) when enabling a browsing
function which carries out prediction analysis.
・Specify N at the 3^rd byte within the range from 0x00 to 0x14(20). Any
other settings will not accept the command.
・The LSI analyzes entries in the number specified by N.
・Since even (0-N) can specify with the parameter of
'READ_BROWSE_INFO', N+1 entry information can be acquired at the
maximum.
・Initial setting is N=0x0A=10 entry prediction analysis.
4 0x60 0x0B N 0x00 ・Specify the number of files predicted by the READ_PFILE_NAME
command.
・A READ_PFILE_NAME command can be predicted only within the same
folder.
・Specify N at the 3^rd byte within the range from 0x00 to 0x5. Any other
settings will not accept the command. The LSI looks ahead files in the
number specified by N.
・Since READ_PFILE_NAME allows you to specify in a range of 0 to N,
you can obtain the information of up to N+1 files.
・Initial setting is N=0x03 file prediction analysis.
4 0x60 0x0D N 0x00 ・Set up LBIT and a copy bit when SPDIF output.
・Select N at the 3^rd byte from the following. Any setting other than
N=0x01 is considered to specify N=0x00.
N=0x00: SPDIF LBIT=1, copy bit = 0 (copy disabled).
N=0x01: SPDIF LBIT=0, copy bit = 1 (copy enabled).
・Initial value is N= 0x00, (ban on a copy).
4 0x60 0x0F N 0x00 ・Set up a USB terminal output.
・Select N at the 3^rd byte from the following. Any other setting is
considered to specify N=0x01.
N=0x00: Normally operating terminal
N=0x01: Outputs a test packet from the USB terminal.
・Initial value is N= 0x00.
4 0x60 0x10 0x00 0x00 ・Analyze the availability of the media selected now.
・The LSI starts analyzing the free space after receiving the command.
During analysis, SEARCH=0x1 is set. Upon completion of analysis,
SEARCH=0x0 is set.
・After analyzing the free space, you can use the READ_DEV_FREE
command to obtain the current free space.
・The LSI does not monitor the free space automatically. Whenever
changing the system operation mode or the selected media, you should
