4.2 Interrupt sources

Table 4.2.1 lists interrupt sources and their vector addresses. When programming, set the start address of

each interrupt routine to the vector addresses listed below.

4.2 Interrupt sources

Interrupt vector addresses

Table 4.2.1 Interrupt sources and Interrupt vector addresses

Notes 1: This is only for debugger control and is not used usually.

2: When the key input interrupt selection bit (bit 7 at address 6D16) = “1,” the key input interrupt

function is selected. For details, refer to chapter “5 KEY INPUT INTERRUPT FUNCTION.”

3: The A-D conversion interrupt and the UART2 transmission/reception interrupt share the same

interrupt vector addresses and interrupt control register. By setting the serial I/O mode selection

bits (bits 0 to 2 at address 6416), the A-D conversion interrupt or UART2 transmission/reception

interrupt is selected.
