22.1.2 Registers controlling standby function
(1) Oscillation stabilization time counter status register (OSTC)
R01UH0008EJ0401 Rev.4.01
Jul 15, 2010
The standby function is controlled by the following two registers.
• Oscillation stabilization time counter status register (OSTC)
• Oscillation stabilization time select register (OSTS)
Remark For the registers that start, stop, or select the clock, see CHAPTER 6 CLOCK GENERATOR.
This is the register that indicates the count status of the X1 clock oscillation stabilization time counter. When X1 clock
oscillation starts with the internal high-speed oscillation clock or subsystem clock used as the CPU clock, the X1 clock
oscillation stabilization time can be checked.
OSTC can be read by a 1-bit or 8-bit memory manipulation instruction.
When reset is released (reset by RESET input, POC, LVI, and WDT), the STOP instruction and MSTOP (bit 7 of MOC
register) = 1 clear OSTC to 00H.
