Tool/software:
The TRM refers to spruim2g.pdf
TRM "6.2.3.5.5 VIM Interrupt Prioritization" states, "If prior to this interrupt being cleared (by writing to the R5FSS_VIM_FIQVEC register, or R5FSS_VIM_IRQVEC register) another interrupt of higher priority arrives,".
However, when I checked TRM "6.2.4.4.8 R5FSS_VIM_FIQVEC Register" and TRM "6.2.4.4.7 R5FSS_VIM_IRQVEC Register," I found that both the R5FSS_VIM_FIQVEC register and R5FSS_VIM_IRQVEC are read-only registers.
In the text it says "(by writing to the R5FSS_VIM_FIQVEC register, or R5FSS_VIM_IRQVEC register)", but I would like to know what it means to write to a read-only register.
Thank you in advance for your help.
