TinyPowerTM A/D Flash Type 8-Bit MCU with LCD & EEPRO

Compact Type TM

Although the simplest form of the three TM types, the Compact TM type still contains three

operating modes, which are Compare Match Output, Timer/Event Counter and PWM Output modes.

The Compact TM can also be controlled with an external input pin and can drive one or two external

output pins. These two external output pins can be the same signal or the inverse signal.

Compact TM Operation

At its core is a 10-bit count-up counter which is driven by a user selectable internal or external clock

source. There are also two internal comparators with the names, Comparator A and Comparator P.

These comparators will compare the value in the counter with CCRP and CCRA registers. The

CCRP is three bits wide whose value is compared with the highest three bits in the counter while the

CCRA is the ten bits and therefore compares with all counter bits.

The only way of changing the value of the 10-bit counter using the application program, is to clear

the counter by changing the TnON bit from low to high. The counter will also be cleared

automatically by a counter overflow or a compare match with one of its associated comparators.

When these conditions occur, a TM interrupt signal will also usually be generated. The Compact

Type TM can operate in a number of different operational modes, can be driven by different clock

sources including an input pin and can also control an output pin. All operating setup conditions are

selected using relevant internal registers.
