UM10912 LPC546xx I/O pin configuration (IOCON) P0[13 to 14] D or I type?

[A_M]

Hi,

in the UM10912 Rev. 2.4 — 11 November 2019 are the PIO0_13 and PIO0_14 mark as type D and I

10.5.1 Type D IOCON registers
Table 252 applies to pins P0[0 to 9], P0[13 to 14], P0[17 to 22], P0[24 to 30], P1[1 to 31], P2[2 to 31], P3[0 to 20], P3[25 to 31], P4[0 to 31], P5[0 to 10].

10.5.2 Type I IOCON registers
Table 253 applies to pins PIO0_13, PIO0_14, PIO3_23, and PIO3_24. See Table 254 for recommended setting for I2C operation.

PIO0_13, PIO0_14, PIO3_23 & PIO3_24 are listed in the Table 256. Type D I/O Control register. and in Table 257. Type I I/O Control registers: FUNC values and pin functions

I gess the PIO0_13, PIO0_14, PIO3_23 & PIO3_24 are all type I Register?

Hello @A_M,

Actually, if you look at those pins (PIO0_13, PIO0_14) in MCUXpresso IDE ConfigTools Pins View, you could see that the IOCON Register for them is Type I.

[PIO0_13, PIO0_14, PIO3_23 and PIO3_2 in ConfigTools Pins View]

You could compare the PIO0_17 that is Type D, against the PIO0_13, PIO0_14, PIO3_23 and PIO3_2 that are Type I.

Best regards, Raul.
