Description
Flash Memory Control Register Enable
Enables or disables CPU access for flash memory
registers (FLMCR1, FLMCR2, EBR1, EBR2), control
registers in power-down state (SBYCR, LPWRCR,
MSTPCRH, MSTPCRL), and control registers of on-
chip peripheral modules (PCSR, SYSCR2).
0: Registers in power-down state and control
1: Control registers of flash memory are accessed in
Reserved
The initial value should not be changed.
Internal Clock Source Select 1, 0
These bits select a clock to be input to the timer
counter (TCNT) and a count condition together with
bits CKS2 to CKS0 in the timer control register
(TCR). For details, refer to section 12.3.4, Timer
Control Register (TCR).
registers of on-chip peripheral modules are
accessed in an area from H'(FF)FF80 to
H'(FF)FF87.
