17.1.1 Connection of INTP1 pin
X1 and X2 pins can be used as I/O port pins or the pins for oscillation, after the monitor program has been written.
Design circuits appropriately according to the relevant case among the cases shown below.
Pins for communication depend on whether the monitor program has been written or not. (refer to Table 17-1)
The INTP1 pin is used only for communication between QB-MINI2 and the target device during debugging.
(1) INTP1 pin is not used in target system (as is illustrated in Figure 17-1.
(2) QB-MINI2 is used only for programming, not for debugging
(3) QB-MINI2 is used for debugging and debugging of the INTP1 pin is performed only with a real machine
Notes 2. This is the pin connection when the X1 and X2 pins are not used in the target system. When using
