



Up to two sets of I

2C modules



Supports Master/Slave mode



Bidirectional data transfer between master and slave



Multi-master bus (no central master)



Arbitration between simultaneously transmitting masters without corruption of serial

data on the bus



Serial clock synchronization allows devices with different bit rates to communicate via

one serial bus



Serial clock synchronization can be used as a handshake mechanism to suspend and

resume serial transfer



Programmable clocks allow versatile rate control



Supports multiple address recognition (four slave addresses with mask option)





12-bit SAR ADC



Up to 8-ch single-ended input or 4-ch differential input



Supports Single mode/Burst mode/Single-cycle Scan mode/Continuous Scan mode



pports 2’ complement/un-signed format in differential mode conversion results



Each channel with an individual result register



Supports conversion value monitoring (or comparison) for threshold voltage detection



Conversion started either by software trigger or external pin trigger



A/D conversion started by PWM center-aligned trigger or edge-aligned trigger



PWM trigger delay function



Supports conversion result with signed format in Differential input and Burst mode



Analog Comparator



Up to four sets of Comparator analog modules



External input or internal band-gap voltage selectable at negative node



Interrupt when compared results change



Power-down wake-up



EBI (External Bus Interface) for external memory-mapped device access



Accessible space: 64 KB in 8-bit mode or 128 KB in 16-bit mode
