Forced
SD 2.5V
Shared pin for the IF count buffer (AC
output) and SEEK/STOP switch (DC
input).
V38 switches among three modes
according to the following voltages.
For FM:
5 V: SEEK mode
2.5 V: Forced SD mode, RDS mode
0 V: Reception mode
For AM (two modes: 0 and 5V)
5 V: SEEK mode
0 V: Reception mode
*When interference from an adjacent
FM frequency is detected:
2.5 V: Use RDS mode.
