13.5 PLIC Registers
Any bits in the following registers marked 0 have no function. When the register is a
read/write register, these bits should be cleared.
Some registers are described that control more than one port. In these cases, parentheses
indicates to which port the control bits relate; for example, LM0(0) is the LM0 bit for
port 0.
13.5.1 B1 Data Receive Registers (P0B1RR–P3B1RR)
All bits in these registers are read only and are set on hardware or software reset.
The PnB1RRs contain the last four frames of data received on channel B1. (P0B1RR is the
B1 channel data for port 0, P1B1RR is B1 for port 1, and so on.) The data are packed from
the least significant byte (LSB), up to the most significant byte (MSB).
These registers are aligned on longword boundaries from MBAR + 0x300 for P0B1RR to
MBAR + 0x30C for P3B1RR. See Section 13.2.3, “GCI/IDL B- and D-Channel Bit
Alignment,” for the frame and bit alignment within the 32-bit word.
