Hi.
Always thank you for your help.
Please tell me below.
I am using KE04.
See `` How to Use Bit-band and BME on the KE04 and KE06 Subfamilies AN4838 ''
An attempt was made to set bit 2,1,0 of port D to 0 using a macro in BME.h.
As described in “3.5 BME Library” in the above application manual
BME_AND (& GPIOD-> PDOR) = ~ ((1u << 2) | (1u << 1) | (1u << 0));
However, there is no GPIOD definition.
According to the manual, the upper 8 bits of the 32-bit area indicated by the GPIOA address are assigned to port D.
So how do you write the bit set clear for port D in the BME library?
Thank you.

Hi jun,
yes, there isn't GPIOD. If you want to set and clear PTD0, PTD1, PTD2, you can write as below
BME_OR(&GPIOA->PDOR) = (0x07<<24);
BME_AND(&GPIOA->PDOR)= ~(0x07<<24);
