Description

Port configuration register

Fields

DRIVE_MODE0

The GPIO drive mode for IO pin 0. Resistive pull-up and pull-down is selected in the drive mode. Note: when initializing IO’s that are connected to a live bus (such as I2C), make sure the peripheral and HSIOM (HSIOM_PRT_SELx) is properly configured before turning the IO on here to avoid producing glitches on the bus. Note: that peripherals other than GPIO & UDB/DSI directly control both the output and output-enable of the output buffer (peripherals can drive strong 0 or strong 1 in any mode except OFF=‘0’). Note: D_OUT, D_OUT_EN are pins of GPIO cell.

0 (HIGHZ): Output buffer is off creating a high impedance input D_OUT = ‘0’: High Impedance D_OUT = ‘1’: High Impedance

1 (RSVD): N/A

2 (PULLUP): Resistive pull up

For GPIO & UDB/DSI peripherals: When D_OUT_EN = 1: D_OUT = ‘0’: Strong pull down D_OUT = ‘1’: Weak/resistive pull up When D_OUT_EN = 0: D_OUT = ‘0’: High impedance D_OUT = ‘1’: High impedance

For peripherals other than GPIO & UDB/DSI: When D_OUT_EN = 1: D_OUT = ‘0’: Strong pull down D_OUT = ‘1’: Strong pull up When D_OUT_EN = 0: D_OUT = ‘0’: Weak/resistive pull up D_OUT = ‘1’: Weak/resistive pull up

3 (PULLDOWN): Resistive pull down

For GPIO & UDB/DSI peripherals: When D_OUT_EN = 1: D_OUT = ‘0’: Weak/resistive pull down D_OUT = ‘1’: Strong pull up When D_OUT_EN = 0: D_OUT = ‘0’: High impedance D_OUT = ‘1’: High impedance

For peripherals other than GPIO & UDB/DSI: When D_OUT_EN = 1: D_OUT = ‘0’: Strong pull down D_OUT = ‘1’: Strong pull up When D_OUT_EN = 0: D_OUT = ‘0’: Weak/resistive pull down D_OUT = ‘1’: Weak/resistive pull down

4 (OD_DRIVESLOW): Open drain, drives low

For GPIO & UDB/DSI peripherals: When D_OUT_EN = 1: D_OUT = ‘0’: Strong pull down D_OUT = ‘1’: High Impedance When D_OUT_EN = 0: D_OUT = ‘0’: High impedance D_OUT = ‘1’: High impedance

For peripherals other than GPIO & UDB/DSI: When D_OUT_EN = 1: D_OUT = ‘0’: Strong pull down D_OUT = ‘1’: Strong pull up When D_OUT_EN = 0: D_OUT = ‘0’: High Impedance D_OUT = ‘1’: High Impedance

5 (OD_DRIVESHIGH): Open drain, drives high

For GPIO & UDB/DSI peripherals: When D_OUT_EN = 1: D_OUT = ‘0’: High Impedance D_OUT = ‘1’: Strong pull up When D_OUT_EN = 0: D_OUT = ‘0’: High impedance D_OUT = ‘1’: High impedance

For peripherals other than GPIO & UDB/DSI: When D_OUT_EN = 1: D_OUT = ‘0’: Strong pull down D_OUT = ‘1’: Strong pull up When D_OUT_EN = 0: D_OUT = ‘0’: High Impedance D_OUT = ‘1’: High Impedance

6 (STRONG): Strong D_OUTput buffer

For GPIO & UDB/DSI peripherals: When D_OUT_EN = 1: D_OUT = ‘0’: Strong pull down D_OUT = ‘1’: Strong pull up When D_OUT_EN = 0: D_OUT = ‘0’: High impedance D_OUT = ‘1’: High impedance

For peripherals other than GPIO & UDB/DSI: When D_OUT_EN = 1: D_OUT = ‘0’: Strong pull down D_OUT = ‘1’: Strong pull up When D_OUT_EN = 0: D_OUT = ‘0’: High Impedance D_OUT = ‘1’: High Impedance

7 (PULLUP_DOWN): Pull up or pull down

For GPIO & UDB/DSI peripherals: When D_OUT_EN = ‘0’: GPIO_DSI_OUT = ‘0’: Weak/resistive pull down GPIO_DSI_OUT = ‘1’: Weak/resistive pull up where ‘GPIO_DSI_OUT’ is a function of PORT_SEL, OUT & DSI_DATA_OUT.

For peripherals other than GPIO & UDB/DSI: When D_OUT_EN = 1: D_OUT = ‘0’: Strong pull down D_OUT = ‘1’: Strong pull up When D_OUT_EN = 0: D_OUT = ‘0’: Weak/resistive pull down D_OUT = ‘1’: Weak/resistive pull up

IN_EN1

Enables the input buffer for IO pin 1
DRIVE_MODE2

The GPIO drive mode for IO pin 2
IN_EN2

The GPIO drive mode for IO pin 3
IN_EN3

Enables the input buffer for IO pin 3
DRIVE_MODE4

The GPIO drive mode for IO pin4
IN_EN4

Enables the input buffer for IO pin 4
DRIVE_MODE5

The GPIO drive mode for IO pin 5
IN_EN5

Enables the input buffer for IO pin 5
DRIVE_MODE6
