Description
R channel operation mode
00b = Disabled, reset R channel PC
01b = Load program to SRAM, reset R channel PC
10b = Run program defined by R_EXEC
11b = Direct control, reset R channel PC
G channel operation mode
00b = Disabled, reset G channel PC
01b = Load program to SRAM, reset G channel PC
10b = Run program defined by G_EXEC
11b = Direct control, reset G channel PC
B channel operation mode
00b = Disabled, reset B channel PC
01b = Load program to SRAM, reset B channel PC
10b = Run program defined by B_EXEC
11b = Direct control, reset B channel PC
