RIN2 SEL
JP4
Jumper pins for setting RIN2 (channel 2 RIN) input.
MUL. TEST
JP5
JP6
JP7
JP8
SYNC1 SEL
JP9
Jumper pins for setting SYNC1 (channel 1 SYNC) input.
INT. SYNC2
SEL
JP10
Jumper pins for setting SYNC2 (channel 2 SYNC) input when JP11 has been
set to INT mode.
The SYNC generator is used only by Oki Electric for test, so it has not been
mounted on the board.
SYNC1
mode is not used.
Analog input mode:
PCM data obtained by converting the analog input
signal from the RIN2 pin will be used for channel 2 RIN data.
PCM input mode:
PCM input data from the RPCMI2 pin will be used
directly for channel 2 RIN data.
Open
External input mode:
The external sync signal from the EXT.SYNC1 pin will
be used for SYNC1. SYNC1 and SCK must be
synchronized, so if EXT.SYNC1 is used then SCK must
also be input externally.
Internal input mode:
Depending on JP19 (INT SYNC SEL), either the
internal sync (SYNC0) or the sync signal from the
sync generator will be used for SYNC1.
SYNC1 mode:
The SYNC1 signal will be used as SYNC2.
SYNC1
mode:
The inverted SYNC1 signal will be used as SYNC2.
This setting is valid only when JP19 (INT SYNC SEL)
has been set to OSC mode.
Not used (used only by Oki Electric for test).
