“R/W” in the R/W column of b0 to b7 in the table for the port input data register (PIDR) in 18.3.3 is corrected to “R”.

•Page 334 of 1209

Descriptions for the port input data register (PIDR) in 18.3.3 are corrected as follows:

Before correction

PIDR indicates individual pin states of port m.

The pin states of port m can be read with the PORTm.PIDR, regardless of the values of PORTm.PDR and PORTm.PMR.

The NMI pin state is reflected in the P35 bit.

The bit corresponding to a pin that does not exist is reserved. A reserved bit is read as undefined and cannot be modified.

After correction

PIDR indicates individual pin states of port m.

The pin states of port m can be read with the PORTm.PIDR, regardless of the values of PORTm.PDR and PORTm.PMR.

The NMI pin state is reflected in the P35 bit.

The bits corresponding to pins that are not listed in Table 18.1 are reserved. The read value of a reserved bit is undefined.

Writing has no effect.

Descriptions for the port mode register (PMR) in 18.3.4 are corrected as follows:

Before correction

corresponding to port m on the 64 pin-product but which do not exist on a product with fewer than 64 pins are reserved.

Write 0 to these bits.

After correction

Each bit of PORTm.PMR corresponds to each pin of port m; pin function can be specified in 1-bit units.

The bits corresponding to pins that are not listed in Table 18.1 and the PORT3.PMR.B5 bit of the input-only P35 pin are

units.

Descriptions for the open drain control register 0 (ODR0) in 18.3.5 are corrected as follows:

Before correction

Bits corresponding to port m on the 64 pin-product but which do not exist on a product with fewer than 64 pins are

reserved. Write 0 to these bits.

After correction

Descriptions for the open drain control register 1 (ODR1) in 18.3.6 are corrected as follows:

Before correction

Bits corresponding to port m on the 64 pin-product but which do not exist on a product with fewer than 64 pins are

reserved. Write 0 to these bits.

The PORT3.ODR1.B2 bit is reserved, because the P35 pin is input only. The bit corresponding to a pin that does not exist

After correction

The bits corresponding to pins that are not listed in Table 18.1 and the PORT3.ODR1.B2 bit of the input-only P35 pin are

units.
