Auto-Poll Programming Example
RF frequency 433.92MHz, bit rate 1kbps, bit width 1ms.
D[19] = 0, AGC fast attack enabled
D[18] = 1, watchdog timer is OFF
D[17] = 0, SQ pin floating, squelch is OFF
D[16] = 0
D[15] = 1, device is placed in autopoll
D[14:12] = 100, sleep time 160ms
D[11:9] = 011, bit check window time 457 μ s with D[4:3]
= 00
D[8:7] = 10, number of consecutive valid bits is 8
D[6:5] = 11, slice level 50%
D[4:3] = 00, demodulator bandwidth = 1.625kHz
D[2:0] = 000, no desense
From MSB to LSB, see Table 5:

voltage on SCLK can go up to V DD + 0.3V without
causing damage. But applying V DD + 0.3V to SCLK can
put the part in an unknown test mode. If this accidently
happens, cycle the power supply to restore the part to
normal operation
