Specifications of LPC47M192-NW

• Lead Free Status / RoHS Status: Compliant

0x61 in Logical Device A. The PME status bits for the GPIOs are cleared on a write of ‘1’. In addition, the
LPC47M192 provides 19 GPIOs that can directly generate an SMI. See the table in the next section.
7.12.5 GPIO PME AND SMI FUNCTIONALITY
The following GPIOs are dedicated wakeup GPIOs with a status and enable bit in the PME status and enable
registers:
The following PME status and enable registers for these GPIOs:
The following GPIOs can directly generate an SMI and have a status and enable bit in the SMI status and enable
registers.
The following SMI status and enable registers for these GPIOs:
The following GPIOs have “either edge triggered interrupt” (EETI) input capability. These GPIOs can generate a
PME and an SMI on both a high-to-low and a low-to-high edge on the GPIO pin. These GPIOs have a status bit in
the MSC_STS status register that is set on both edges. The corresponding bits in the PME and SMI status registers
are also set on both edges.
The following table summarizes the PME and SMI functionality for each GPIO.
Triggered Interrupt (EETI) input capability for the GPIOs and the power source for the buffer on the I/O pads.
Note 1: GP35 and GP53 have the IRTX function and their output buffers are powered by VTR so that the
