Bits 2 to 0: Clock Select 2 to 0 (CKS2 to CKS0): These bits select one of eight internal clock

sources, obtained by dividing the system clock (ø), for input to TCNT.

Note: * The overflow period is the time from when TCNT starts counting up from H'00 until overflow

RSTCSR is an 8-bit readable/writable* register that controls the generation of the internal reset

signal when TCNT overflows, and selects the type of internal reset signal.

RSTCSR is initialized to H'1F by a reset signal from the RES pin, but not by the WDT internal

reset signal caused by overflows.

Note: * The method for writing to RSTCSR is different from that for general registers to prevent

Initial value

Note: * Can only be written with 0 for flag clearing.
