6. EEPROM Table
1. After power on, PAW3203DI will check EEPROM, if EEPROM address = 0x01 and data = 0xAA, continue
to read EEPROM address 0x02.
2. When reading successive data is zero, PAW3203DI stops to read data from EEPROM.
3. Placing updated address and data continuously.

80H Sleep1 entry time
17H 8.88ms * 23 = 200ms
81H Sleep1 period
1CH 1ms * (28+2) = 30ms (Refer to the Figure 10)
82H Sleep1 pd low time to check sensor motion status 05H 1ms * 5 = 5ms (Refer to the Figure 10)
83H Sleep2 pd low time to check sensor motion status 05H 1ms * 5 = 5ms (Refer to the Figure 10)
84H Sleep2 entry time
3CH 1s * 60 = 60s
85H Sleep2 period (6bits, range: 0~63)
28H 8ms * (40 + 1) = 328ms (Refer to the Figure 10)
86H Manchester code 1T time (8051 timer0 timer) D8H 4us * (FFH - D8H) = 160us
87H Preamble total time
0FH 1T * 15 = 15T
88H Preamble counts
