13. Key-on Wakeup (KWU)
13.3 Function
TMP86C847UG
Also, each level of the STOP2 to STOP5 pins can be confirmed by reading corresponding I/O port data register,
check all STOP2 to STOP5 pins "H" that is enabled by STOPCR before the STOP mode is startd (Note2,3).
Note 1: When the STOP mode released by the edge release mode (SYSCR1<RELM> = “0”), inhibit input from STOP2 to
STOP5 pins by Key-on Wakeup Control Register (STOPCR) or must be set "H" level into STOP2 to STOP5 pins
that are available input during STOP mode.
Note 2: When the
STOP
pin input is high or STOP2 to STOP5 pins inputwhich is enabled by STOPCR is low, executing an
instruction which starts STOP mode will not place in STOP mode but instead will immediately start the release
sequence (Warm up).
Note 3: The input circuit of Key-on Wakeup input and Port input is separatedAso each input voltage threshold value is
diffrent. Therefore, a value comes from port input before STOP mode start may be diffrent from a value which is
detected by Key-on Wakeup input (Figure 13-2).
Note 4:
STOP
pin doesn’t have the control register such as STOPCR, so when STOP mode is released by STOP2 to
STOP5 pins,
STOP
pin also should be used as STOP mode release function.
Note 5: In STOP mode, Key-on Wakeup pin which is enabled as input mode (for releasing STOP mode) by Key-on
Wakeup Control Register (STOPCR) may genarate the penetration current, so the said pin must be disabled AD
conversion input (analog voltage input).
Note 6: When the STOP mode is released by STOP2 to STOP5 pins, the level of
STOP
pin should hold "L" level (Figure
13-3).
