Datasheet

NOTE

When configuring IIC to use SDA(PTA2) and SCL(PTA3)

pins, if an application uses internal pullups instead of external

pullups, the internal pullups remain present setting when the

pins are configured as outputs, but they are automatically

disabled to save power when the output values are low.

2.2.10 High current drive pins (PTB4, PTB5, PTD0, PTD1, PTE0,

PTE1, PTH0, PTH1)

When high current function is enabled, PTB4, PTB5, PTD0, PTD1, PTE0, PTE1, PTH0

and PTH1 can drive output current. Each high current drive pin can drive higher sink/

source current than the other normal pins, please refer to data sheet for the drive capacity.

2.2.11 Peripheral pinouts

These MCUs support up to 57 general-purpose I/O pins, which are shared with on-chip

peripheral functions (FTM, ACMP, ADC, SCI, SPI, IIC, KBI, etc.). These 57 general-

purpose I/O pins include one output-only pin (PTA4).

When a port pin is configured as general-purpose input, or when a peripheral uses the

port pin as an input, the software can enable a pullup device.

When a high current drive port pin is configured as general-purpose output or when a

peripheral uses the port pin as an output, software can select alternative drive strengths.

For information about controlling these pins as general-purpose I/O pins, see the Parallel

input/output. For information about how and when on-chip peripheral systems use these

pins, see the appropriate module chapter.

Immediately after reset, all pins are configured as high-impedance general-purpose IO

with internal pullup devices disabled.
