FLG—Command Semaphore Flag
The bit is set by the core and cleared by the communication processor module.
16.2.6.2 COMMAND DEFINITIONS. The RISC microcontroller requires an opcode and a
channel number to determine the command to issue. These opcodes and their definitions
are described below. The opcodes and channel numbers that appear in Table 16-2 are
actually the commands to be issued in the CPCR.
NOTE: — = Reserved.
