Bit 3—Oscillation Circuit Feedback Resistance Control Bit (RFCUT): This bit turns the
internal feedback resistance of the main clock oscillation circuit ON/OFF.

Bit 2—Reserved: Only write 0 to this bit.
23B.2.4 Timer Control/Status Register (TCSR)
Notes: 1. Only write 0 to clear the flag.
TCSR is an 8-bit read/write register that selects the clock input to WDT1 TCNT and the mode.
Here, we describe bit 4. For details of the other bits in this register, see section 12.2.2, Timer
Control/Status Register (TCSR).
The TCSR is initialized to H'00 at a reset and when in hardware standby mode. It is not initialized
in software standby mode.

Description
When the main clock is oscillating, sets the feedback resistance ON. When the main
clock is stopped, sets the feedback resistance OFF.
Sets the feedback resistance OFF.
H8S/2635 Group. In versions other than the U-mask and W-mask versions, and
H8S/2635 Group, however, the PSS bit must always be written with 0 since no subclock
functions are available.
