5.3. PWM
2 PWMs can be driven by internal PWM module.
5.4. UART
This is a standard UART interface for communicating with other serial devices. The
UART interface provides a simple mechanism for communicating with other serial
devices using the TTL protocol.
When using low-power mode, TXD needs to pull up resistance, and the reference value
is 4.7k.
Main features are:
Programmable baud rate can reach up to 921600bps.
me of 5, 6, 7 or 8 bits of data.
-parity bit generation and detection.
5.5. I2C Master
The module can act as an I2C master when configured by software.
Main features are:
e and up to 100 Kb/s in standard mode.
multi-master system with bus arbitration.
5.6. SPI Master
The module can act as an SPI master (mode 0) when configured by software.
Main features are:
