D[15..0]
PIOD[47..32]
GPIO pin output data specification
1 : High
0 : Low
This register is used to set the output level for GPIO pins. The PIOD[47..32] bits correspond to the GPIO[47..32]
pins.
The data written to the PIOD bit is output via the corresponding GPIO pin. The set value can be read by reading
the PIOD bit.
Pins set by this register are output-only. Pins set by this register are used exclusively from other function pins.
Therefore, when using this register, set the enable bit to prohibit in the corresponding unit.
The correspondences between PIOD bits and function pins are listed in the table on the next page.
