Description amended
• Module standby function (TMU, RTC, SCI/SCIF, DMAC,
SQ*, and UBC* )
Description amended
Bit 6 —STATUS Pin High-Impedance Control (STHZ): This bit
selects whether the STATUS0 and STATUS1 pins are set to
high-impedance when in hardware standby mode.
Bit 6: STHZ
0
1
Description
Sets STATUS0, 1 pins to high-impedance when in hardware standby mode
(Initial value)
Drives STATUS0, 1 pins to LH when in hardware standby mode

Hardware Standby
Mode
Notes amended
Notes: 1. Only when the RTC clock (32.768 kHz) is operating
(see section 19.2.2, IRL Interrupts), standby mode
can be exited by means of IRL3–IRL0 (when the
IRL3–IRL0 level is higher than the SR register IMASK
mask level).
2. GPIO can be used to cancel standby mode when the
RTC clock (32.768 kHz) is operating (when the GPIO
level is higher than the SR register IMASK mask
level).
Description amended
3. On the SH7750S, the RTC continues to operate even when
no power is supplied to power pins other than the RTC power
supply pin.
The state of the STATUS pin reflects the setting of the STHZ
bit. Refer to appendix E, Pin Functions, for details on output
pin states.
