163 / 221 page  2016-2017 Microchip Technology Inc. DS00002084C-page 163 UPD360 11.4.4 PD MAC BMC ENCODER/DECODER REGISTERS The following sub-sections describe the various registers associated with the PD MAC BMC Encoder/Decoder. 11.4.4.1 BMC RX High Level Full Bit Maximum Time Register (BMC_RX_HI_FB_MAX_TIME) The value of this register together with the value of the BMC RX High Level Full Bit Minimum Time Register (BMC_RX- _HI_FB_MIN_TIME) is used by the BMC decoder to determine the valid full bit time for a high level RX signal. This time should take into account both the bit rate range and duty cycle distortion of the received signal. BMC_RX_HI_FB_MAX_TIME > valid high time > BMC_RX_HI_FB_MIN_TIME 11.4.4.2 BMC RX High Level Full Bit Minimum Time Register (BMC_RX_HI_FB_MIN_TIME) The value of this register together with the value of the BMC RX High Level Full Bit Maximum Time Register (BMC_RX- _HI_FB_MAX_TIME) is used by the BMC decoder to determine the valid full bit time for a high level RX signal. This time should take into account both the bit rate range and duty cycle distortion of the received signal. BMC_RX_HI_FB_MAX_TIME > valid high time > BMC_RX_HI_FB_MIN_TIME BMC_RX_HI_FB_MIN_TIME > BMC_RX_HI_HB_MAX_TIME 11.4.4.3 BMC RX Low Level Full Bit Maximum Time Register (BMC_RX_LO_FB_MAX_TIME) The value of this register together with the value of the BMC RX Low Level Full Bit Minimum Time Register (BMC_RX- _LO_FB_MIN_TIME) is used by the BMC decoder to determine the valid full bit time for a low level RX signal. This time should take into account both the bit rate range and duty cycle distortion of the received signal. BMC_RX_LO_FB_MAX_TIME > valid low time > BMC_RX_LO_FB_MIN_TIME Address: 1AA0h Size: 8 bits Bits Description Type Default 7:0 BMC_RX_HI_FB_MAX_TIME Time in clock cycles at minimum bit-rate and worst duty cycle distortion. = (((clock_freq_KHz / min_bit_rate_Kbps) * (100 + tolerance) / 100) - 1) Note: A value of 202 (decimal) is recommended for this field. R/W 00h Address: 1AA1h Size: 8 bits Bits Description Type Default 7:0 BMC_RX_HI_FB_MIN_TIME Time in clock cycles at maximum bit-rate and worst duty cycle distortion. = (((clock_freq_KHz / max_bit_rate_Kbps) * (100 - tolerance) / 100) - 1) Note: A value of 116 (decimal) is recommended for this field. R/W 00h Address: 1AA2h Size: 8 bits Bits Description Type Default 7:0 BMC_RX_LO_FB_MAX_TIME Time in clock cycles at minimum bit-rate and worst duty cycle distortion. = (((clock_freq_KHz / min_bit_rate_Kbps) * (100 + tolerance) / 100) - 1) Note: A value of 202 (decimal) is recommended for this field.
