Note:
1. For the System Start-up time values, whether f
SYS
is on or off depends upon the mode type and the chosen
f
SYS
system oscillator. Details are provided in the System Operating Modes section.
2. The time units, shown by the symbol t
HIRC
etc. are the inverse of the corresponding frequency values as
provided in the frequency tables. For example t
HIRC
=1/f
HIRC
, t
SYS
=1/f
SYS
etc.
3. If the LIRC is used as the system clock and if it is off when in the SLEEP Mode, then an additional LIRC start
up time, t
START
, as provided in the LIRC frequency table, must be added to the t
SST
time in the table above.
4. The System Speed Switch Time is effectively the time taken for the newly activated oscillator to start up.

Note: The R
PH
internal pull high resistance value is calculated by connecting to ground and enabl
ing
the input pin
with
a
pull-high resistor and then measuring the pin current at the specified supply voltage level. Dividing
the voltage by this measured current provides the R
PH
value.
