8.1.6
ODR is an 8-bit readable/writable register that selects the open-drain output function.
If a bit in ODR is set to 1, the pin corresponding to that bit in ODR functions as an NMOS open-
drain output. If a bit in ODR is cleared to 0, the pin corresponding to that bit in ODR functions as
a CMOS output.
The initial value of ODR is H'00.
8.1.7
PHRTIDR stores the status of port H using pin IRQ14 as a trigger. The detection method is
specified by the IRQ14SR and IRQ14SF bits in the IRQ sense control register H (ISCRH) and is
selected from a low level, a falling edge, a rising edge of pin, and both edges of pin IRQ14. For
details, see section 5.3.5, IRQ Sense Control Registers H and L (ISCRH and ISCRL).
