In the table above some ISR names (shaded) are given symbolically in the interest of brevity,

representing multiple possible ISR names. The table below describes how to interpret the symbolic ISR

Key to Symbolic ISR Names

Symbolic ISR Name

Replace TIMER# with the name of the I/O Timer, e.g. TIMER1.

Replace TIMER* with the applicable 16-bit timer name, e.g. TIMER4.

Replace TIMER& with the software UART timer name, e.g. TIMER2.

Replace TIMER$ with the RTC timer name, e.g. TIMER0.

Replace TC* with the applicable timer name, e.g. TCC0.

Replace TC$ with the software UART timer name, e.g. TCC0.

Replace TC$ with the RTC timer name, e.g. TCC0.

Replace USART# with the applicable UART name, e.g. USART0.

Replace USART# with the applicable UART name, e.g. USARTC0.

Replace INT# with the external interrupt name, e.g. INT0.

Replace INT* with the X-10 zero-crossing interrupt name, e.g. INT0.

Replace PCINT# with the pin change interrupt name, e.g. PCINT0.

Replace PORTx with the applicable port name, e.g. PORTA and replace

INT# with the applicable pin change channel designator, e.g. INT0.

Program Memory Page Size

For ZBasic devices having Program Memory in internal Flash Memory, the page size of that memory is an

important value. For example, for an application that writes to Program Memory a buffer of the length of

the page size must be allocated from the heap in order to perform the necessary read-modify-write

operation that is required for updating Flash Memory locations. This is one factor affecting the minimum
