• Mode 7
… For reduced current and hence power consumption,
fix (pull up/pull down/connect to power supply/connect
to ground) the EXTAL pin and open the XTAL pin when
the LSI is used in mode 7.
83 Description amended.
A PLL settling time is required when the multiplication
rate of oscillation circuit 1 is changed. The on-chip
WDT counts the settling time. The oscillation
stabilization time becomes the same time as that of
recovery from the software standby mode.
85 Description amended.
Figure 3.2 is an example of connecting the external
clock input. When putting the XTAL pin in open state,
make sure the parasitic capacitance is less than or
equal to 10 pF. To stably input the external clock with
enough PLL stabilizing time at power on or releasing
the standby, wait longer than the oscillation stabilizing
time.
86 Description amended.
In the PLLVcc and PLLVss connection pattern for the
PLL, signal lines from the board power supply pins
must be as short as possible and pattern width must be
as wide as possible to reduce inductive interference.
In clock operating mode 7, the EXTAL pin is pulled up
and the XTAL pin is left open.
Since the analog power supply pins of the PLL …

4.2.4 Manual Reset
(1) Manual Reset by Means of
MRES Pin
96 Description amended.
When the MRES pin is driven low, this LSI enters the
manual reset state. To reset this LSI without fail, the
MRES pin should be kept at the low level for at least
20-tcyc. In the manual reset state …
