3.7 RTC.1: An RTC match doesn’t drive the ONSW pin active (HIGH)
3.8 INT.1: GPI_08 does not generate an interrupt signal
Introduction:
An ONSW output pin (M15) is included in the LPC3250 to assist in waking up the chip
after power is removed from all functions except the RTC and Battery RAM. When there is
an active match condition the RTC will drive the ONSW pin HIGH. The RTC only drives
the ONSW pin while the match is active, and after 1 second of active match, if the
software has not accessed the RTC block, the ONSW pin will go low when the match is no
longer active.
Problem:
When power is removed from all functions except the RTC and Battery RAM, the RTC
does NOT drive the ONSW pin HIGH when there is an active match condition.
Work-around:
There is no work-around for this problem.
Introduction:
The LPC3250 contains 12 pins (GPI_00 - GPI_09, GPI_19, GPI_28 ) that function as
dedicated General Purpose Inputs. Each of these pins can generate an individual interrupt
for the input pin. Sub Interrupt Controller Register 1 (SIC1_ER) and Sub Interrupt
Controller Register 2 (SIC2_ER) contains bits that allow enabling or disabling the interrupt
for the associated pin.
Problem:
When bit nine is set to one in the Sub Interrupt Controller 2 Enable register (SIC2_ER[9])
it does not enable the interrupt for the GPI_08 pin. All other General Purpose Input pins
(GPI_00 - GPI_07, GPI_09, GPI_19, GPI_28) interrupts work correctly.
Work-around:
There is no work-around for this problem.
