Notes on bit operation
(This note applies to the R8C/3x Series and R8C/Lx Series.)
Set the following bits with consecutive instructions. Do not allow interrupts or DTC transfer to occur between executing
instructions.
(1) PRC2 bit:
(2) Bits CSPRO, FMR01, FMR02, FMR13, FMR20, FMR22, and FMR27:
(3) Bits FMR14, FMR15, FMR16, and FMR17:
The PRC2 bit becomes 0 after setting it to 1 (write enabled) and writing to an SFR area. Write to the register
protected by the PRC2 bit with the next instruction after that used to set the PRC2 bit to 1. Do not allow interrupts
or DTC transfer between the instruction to set to the PRC2 bit to 1 and the next instruction.
When setting these bits to 1, write 0 immediately followed by 1. Do not allow interrupts and DTC transfer to occur
between writing 0 and writing 1.
When setting these bits to 0, write 1 immediately followed by 0. Do not allow interrupts and DTC transfer to occur
between writing 1 and writing 0.
