NOTES:
1. Although the SYM register is not used, SYM.5 should always be "0". If you accidentally write a 1 to this bit during normal
operation, a system malfunction may occur.
2. Except for T0CNTH, T0CNTL, IRQ, T1CNTH, T1CNTL, T2CNTH, T2CNTL, and BTCNT, which are read-only, all registers
in set 1 are read/write addressable.
3. You cannot use a read-only register as a destination field for the instructions OR, AND, LD, and LDB.
