13.2.11 Refresh Timer Control/Status Register (RTCSR)
The refresh timer control/status register (RTCSR) is a 16-bit readable/writable register that
specifies the refresh cycle and whether interrupts are to be generated.
RTCSR is initialized to H'0000 by a power-on reset, but is not initialized by a manual reset or in
standby mode.
Bits 15 to 8—Reserved: These bits are always read as 0. For the write values, see section 13.2.15,
Notes on Accessing Refresh Control Registers.
