•
Duty cycle: Selectable from options: 1/2, 1/3 and 1/4
•
Bias: Fixed at 1/3
•
Frame period: Selectable from four options. (for clock, peripheral clock or subclock is selectable)
•
Driver: Built-in (for internal divided resistors), or external divided resistors can be connected to the
V0-V3 pins
•
Data memory: Built-in 16-byte data memory for display

•
Adjustable watchdog timer interval (between 2
20
and 2
26
system clock cycles)
• RC oscillator watchdog timer (16 bits)
• Real-time clock (counts during stop mode)
•
RTC module can be clocked either from 32 kHz crystal, 4 MHz quartz or from the RC Oscillator
•
Facility to correct oscillation deviation (subclock calibration)
•
Read/write accessible second/minute/ hour registers
•
Can signal interrupts every halfsecond/second/ minute/hour/day
•
Internal clock divider and prescaler provide exact 1s clock based on a 4 MHz or a 32 kHz clock input
•
Prescaler value for 4 MHz is 0F423F
