7. I/O Ports
Port 7 Data Register (P7DR)
When port 7 is read, the pin logic levels are always read. P7DR cannot be modified.
7.5
7.5.1
Port 8 is a 5-bit input/output port that is also used for CS
A/D converter ADTRG input. Figure 7.4 shows the pin configuration of port 8.
In the H8/3008, port 8 can provide CS
table 7.8 for the selection of pin functions in expanded modes.
See section 14, A/D Converter, for a description of the A/D converter's ADTRG input pin.
The IRQ
input or output. Caution is therefore required. For details see section 5.3.1, External Interrupts.
Pins in port 8 can drive one TTL load and a 90-pF capacitive load. They can also drive a
darlington transistor pair.
