Table 2. Register Bit Formats
MR1 (Mode Register 1)
NOTE: *In block error mode, block error conditions must be cleared by using the error reset command (command 4x) or a receiver reset.
MR2 (Mode Register 2)
CR (Command Register)
SR (Status Register)
2006 Aug 07
NOTE: *Add 0.5 to values shown above for 0–7, if channel is programmed for 5 bits/char.
NOTE: Access to the upper four bits of the command register should be separated by three (3) edges of the X1 clock. A disabled transmitter
cannot be loaded
NOTE: *These status bits are appended to the corresponding data character in the receive FIFO. A read of the status register provides these
bits [7:5] from the top of the FIFO together with bits [4:0]. These bits are cleared by a reset error status command. In character mode, they
must be reset when the corresponding data character is read from the FIFO. In block error mode, block error conditions must be cleared by
using the error reset command (command 4x) or a receiver reset.
