LPC845 PIO0_30 missing

lubomirbogdanov — Tue, 22 Oct 2019 18:25:43 GMT

Hello guys,

If I go to the LPC845 datasheet on page 8, fig. 5, the LQFP48 package has a pin number 42 which corresponds to PIO0_30. If I go to the LPC845 user guide in section 11.5 I/O configuration register description, I cannot find such a pin.

If I go to PIO1_30 in that same document I see a table name:

Table 250. PIO0_30 register (PIO0_30, address 0x4004 40CC) bit description

So which one is true? I'm a bit confused.

Thanks in advance,

L. B.

Hi Lubomir Bogdanov,

Thank you for your interest in NXP Semiconductor products and
for the opportunity to serve you.
In section 11.5 I/O configuration register description of LPC845's user guide, the Table 199 contains the PIO0_30 actually.

OK, I see!

Can we say that the register PIO1_30 has the same structure of the bit fields as PIO0_30?

Hi Lubomir Bogdanov,

Thanks for your reply.
Actually, the LPC845 series don't have the PIO1_31 pin.
