Note 1: The value of SYSCR3<RAREA> is invalid until 0xD4 is written into SYSCR4.
Note 2: To assign vector address areas to RAM, set SYSCR3<RVCTR> to "1" and SYSCR3<RAREA> to "1".
Note 3: Do not set SYSCR3<RVCTR> to "0" by using the RAM loader program. If an interrupt occurs with SYSCR3<RVCTR> set
Note 4: Bits 7 to 3 of SYSCR3 are read as "0".
Note 1: SYSCR4 is a write-only register, and must not be accessed by using a read-modify-write instruction, such as a bit oper-
