DMA Controller
5.
This is a descriptor-type MA controller whose transfer parameters are arranged in the main memory.
A maximum of 8 factors in total (internal and external) can be transferred.
External factors are 3 channels.
Bit Search Module

10. Serial I/O
UART
×
5 channels; clock synchronous serial transfer with LSB / MSB switching function is possible for both.
Serial data output or serial lock output can be selected using push-pull / open-drain software.
11. Level Comparator Input
1 channel; shared input and pins of A/D converter.
12. Clock Switching Function
Base clock : Software can be used to select from two types of clock sources, namely 32 kHz and high-speed.
Gear function : Four types of settings (1 : 1, 1 : 2, 1 : 4, 1 : 8) can be set individually as the operating clock
ratio to the basic clock per CPU and peripheral equipment.
