GPT1
GPT2
General Purpose Timer Timer Peripherals Each GPT is a 32-bit “free-running” or “set and forget”
mode timer with programmable prescaler and compare
and capture register. A timer counter value can be
captured using an external event and can be configured
to trigger a capture event on either the leading or trailing
edges of an input pulse. When the timer is configured to
operate in “set and forget” mode, it is capable of
providing precise interrupts at regular intervals with
minimal processor intervention. The counter has output
compare logic to provide the status and interrupt at
comparison. This timer can be configured to run either
on an external clock or on an internal clock.
KPP Keypad Port Human Machine
Interfaces
The KPP is a 16-bit peripheral that can be used as a
keypad matrix interface or as general purpose
input/output (I/O). It supports 4 x 4 external key pad
matrix. Main features are:
• Multiple-key detection
• Long key-press detection
• Standby key-press detection
• Supports a 2-point and 3-point contact key matrix
LPI2C1
LPI2C2
Low Power
Inter-integrated Circuit
Connectivity and
Communications
The LPI2C is a low power Inter-Integrated Circuit (I2C)
module that supports an efficient interface to an I2C bus
as a master.
The I2C provides a method of communication between
a number of external devices. More detailed
information, see Section 4.8.2, LPI2C module timing
parameters.
LPSPI1
LPSPI2
Low Power Serial
Peripheral Interface
Connectivity and
Communications
The LPSPI is a low power Serial Peripheral Interface
(SPI) module that support an efficient interface to an
SPI bus as a master and/or a slave.
• It can continue operating while the chip is in stop
modes, if an appropriate clock is available
• Designed for low CPU overhead, with DMA off
loading of FIFO register access
LPUART1
LPUART2
LPUART3
LPUART4
UART Interface Connectivity
Peripherals
Each of the UART modules support the following serial
data transmit/receive protocols and configurations:
• 7- or 8-bit data words, 1 or 2 stop bits, programmable
parity (even, odd or none)
• Programmable baud rates up to 5 Mbps.
MQS Medium Quality Sound Multimedia
Peripherals
MQS is used to generate 2-channel medium quality
PWM-like audio via two standard digital GPIO pins.
