CONFIGURATION PACKET
The Configuration Packet defines a number of different configuration options for the S5T8701. Proper operation
is not guaranteed if these settings are changed when decoding is enabled (i.e. the
ON
bit in the Control Packet is
set). The ID of the Configuration Packet is 1.

DFC:
Disable Fractional Clock. When this bit is set and IDE is set, the CLKOUT signal will generate a
40kHz signal (EXTAL divided by 4). When this bit is cleared and IDE is set, the CLKOUT signal will
generate 38.4kHz signal (EXTAL fractionally divided by 25/6 see diagram below). This bit has no
effect when IDE is cleared. (value after reset=0)

IDE:
Internal Demodulator Enable. When this bit is set , the internal demodulator is enabled and clock
frequency at EXTAL is expected to be 160kHz. When this bit is cleared, the internal demodulator is
disabled and the clock frequency at
EXTAL
is expected to be 76.8kHz.(value after reset=0)
