Bit 3—Flash Memory Control Register Enable (FLSHE): Controls CPU access to the flash
memory control registers (FLMCR1, FLMCR2, EBR1, and EBR2), the power-down mode control
registers (SBYCR, LPWRCR, MSTPCRH, and MSTPCRL), and the supporting module control
registers (PCSR and SYSCR2).
Bit 2—Reserved: Do not write 1 to this bit.
Bits 1 and 0—Internal Clock Select 1 and 0 (ICKS1, ICKS0): These bits, together with bits
CKS2 to CKS0 in TCR, select the clock to be input to TCNT. For details, see section 12.2.4,
Timer Control Register (TCR).
