ID RESISTANCE VALUE ASSIGNMENT
The ID resistors used with the 34827 are standard 1%
resistors. Table 32 shows a table of standard E96 resistor
Table 31. ADC Output and ID Resistor Values for Remote
Control Buttons (Unit: k Ω )
values.
The ADC Result values vs. all 32 ID-resistance values are
listed in Table 6 . Table 31 shows the remote control buttons
vs. the ADC Result values and the ID-resistance values.
These functions are tentative and will be decided by
Samsung. The remote control architecture is illustrated in
Figure 37 . The recommended resistors for the remote control
resistor network are given in Table 30 .
Table 33 lists the complete 32 ID-resistor assignment. The
ones with the Assigned Functions filled are the ones that are
already used. The ones reserved can be assigned to other
functions.
