The PB pin is a dedicated digital input. In addition, if the optical UART is not used, OPT_TX and OPT_RX can be configured
as dedicated DIO pins. Thus, in addition to the 16 general-purpose DIO pins (DIO4…DIO11, DIO14…DIO21), there are three
additional pins that can be used for digital input and output.

LCD Drivers
The device in the 68-pin QFN package contains 20 dedicated LCD segment drivers in addition to the 18 multi-use pins
described above. Thus, the device is capable of driving between 80 to 152 pixels of LCD display with 25% duty cycle (or 60 to
114 pixels with 33% duty cycle). At eight pixels per digit, this corresponds to 10 to 19 digits.
The device in the 64-pin LQFP package contains 20 dedicated LCD segment drivers in addition to the 15 multi-use pins
described above. Thus, the device is capable of driving between 80 to 140 pixels of LCD display with 25% duty cycle (or 60 to
105 pixels with 33% duty cycle). At eight pixels per digit, this corresponds to 10 to 17 digits.
The LCD drivers are grouped into four commons and up to 38 segment drivers (68-pin package), or 4 commons and 35
segment drivers (64-pin package). The LCD interface is flexible and can drive either digit segments or enunciator symbols.
Segment drivers SEG18 and SEG19 can be configured to blink at either 0.5Hz or 1Hz. The blink rate is controlled by LCD_Y.
There can be up to four pixels/segments connected to each of these drivers. LCD_BLKMAP18[3:0] and LCD_BLKMAP19[3:0]
identify which pixels, if any, are to blink.
