3.5 Count Registers
Note: Bit 2 of Control Register 4 determines if the addresses point to the bit count or error count registers.
The bit count registers comprise a 48-bit count of bits (actually RCLK cycles) received at RDAT. C47 is
the MSB of the 48-bit count. The bit counter increments for each cycle of RCLK when RCLK_EN is
high. The bit counter is enabled regardless of synchronization. The status register bit BCOF is set when
this 48-bit register overflows. The counter rolls over upon an overflow condition. The DS2174 latches the
bit count into the bit count registers and clears the internal bit count when the LC bit in Control Register 1
is toggled from low to high.
The error count registers comprise a 48-bit count of bits received in error at RDAT. The bit error counter
is disabled during loss-of-sync. C47 is the MSB of the 48-bit count. The status register bit BECOF is set
when this 48-bit register overflows. The counter rolls over upon an overflow condition. The DS2174
latches the bit count into the bit error count registers and clears the internal bit error count when the LC
bit in Control Register 1 is toggled from low to high.
The bit count and bit error count registers are used by an external processor to compute the BER
performance on a loop or channel basis.
