5.1.65 I/O Buffer Type Configure Register (BTCR)

Offset 15H (Read/Write)

Field

Name

Description (Default = 00h)

Always write zero

PME_IQR_EN PME interrupt enable

0: PME interrupt disable (Default)

1: PME interrupt enable

IRQ_TYPE

Interrupt I/O Buffer Type

0: Enable IRQ to function as an open-drain buffer for use in a wired-OR interrupt

configuration. And ignored INTP field, the interrupt output is always active low.

(Default)

1: IRQ output is a Push-Pull driver

IRQ_POL

Interrupt Polarity

0: Low active (Default)

1: High active

Reserved

PME_IND

PME indication

0: A static signal active when detect wake-up event. (Default)

1: A 60ms pulse active when detect wake-up event.

PME_TYPE

PME I/O Type. When cleared, PME_POL is ignored, and the output is always active

low.

0: PME to function as an open-grain buffer for use in a wired-or configuration.

(Default)

1: PME output is a Push-Pull driver.

PME_POL

PME Polarity.

0: PME active Low (Default)

1: PME active high (ignore when PME_TYPE is low)
