LCCR is a 16-bit counter that indicates the number of times the carrier was lost during data
transmission. When the value in this register reaches H'FFFF (65,535), the count is halted. The
counter value is cleared to 0 by a write to this register (the write value is immaterial).
Bits 31 to 16—Reserved: These bits are always read as 0. The write value should always be 0.
Bits 15 to 0—Lost Carrier Count 15 to 0 (LCC15 to LCC0): These bits indicate the number of
times the carrier was lost during data transmission.
