MASK OPTION SELECTION

The following mask options are provided with the pins.
(1) Pull-up/pull-down resistor selection
Pins
P40-P43
P50-P53
P120-P123
P130-P133
P140-P143
P90-P93
(2) Feedback resistor selection for the subsystem clock oscillation
Pins
XT1, XT2
Note: The operation is not affected if the feedback resistor is selected when the subsystem
clock is not used. However, the supply current I
