Preliminary
Mask option
The following shows many kinds of mask options in the HTG2150. All the mask options must be de-
fined on order to ensure proper system functioning.
No.
Mask Option
1
WDT enable/disable selection.
WDT can be enabled or disabled by mask option.
2
Wake-up selection. This option defines the wake-up activity. External I/O pins (PA only)
all have the capability to wake-up the chip from a HALT mode by a following edge.
3
External interrupt input pin share with other function selection.
INT/SEG37: INT can be set as an external interrupt input pin or LCD segment output
pin.
4
I/O pins share with other function selection.
PB4/SEG33, PB5/SEG34, PB6/SEG35, PB7/SEG36: PB4, PB5, PB6, PB7 can be set as
I/O pins or LCD segment output pins.
5
Segment output pins share with other function selection.
XIN/SEG39, XOUT/SEG38: SEG38, SEG39 ban be set as LCD segment output pins or
XIN, XOUT pins be connected to a 32768Hz crystal.
6
LCD bias register selection. This option describes the LCD bias current. There are three
types of selection. *
Selectable as small, middle or large current.
