Section 11 I/O Ports
11.16.5 Pin Functions
Port H pins also function as bus control signal I/Os and interrupt inputs. The correspondence
between the register specification and the pin functions is shown below.
• PH3/CS7/OE-A/CKE-A/IRQ7-B
• Modes 1, 2, 4, and 3, 5, 7 (EXPE = 1)
• Modes 3, 5, and 7 (EXPE = 0)
Notes: 1. IRQ7-B input when the ITS7 bit in ITSR is 1.
