10.16.4 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.
Note: Only modes 1 and 2 are supported on ROM-less versions.
• PH3/CS7/OE/CKE *
Notes: 1. IRQ7 interrupt input pin when bit ITS7 is set to 1 in ITSR
• PH2/CS6/(IRQ6)
