Key-on Wakeup Circuit
Dynamic pull-up operation is executed as shown below.
Pull-up is executed only in the T1 period determined by <T1S1:0>. Pull-up is not executed in the
remaining period.
Dynamic pull-up operation is repeated in the T2 cycle determined by <T2S1:0>.
・
・
fs must be operated while dynamic pull-up is used.
Key input must be started during the second T1 period after enabling dynamic
pull-up.
