RX23W Group 44. 12-Bit A/D Converter (S12ADE)

Note 1. The peripheral module clock PCLK frequency is set according to the setting of the SCKCR.PCKB[3:0] bits and the A/D

conversion clock ADCLK frequency is set according to the setting of the SCKCR.PCKD[3:0] bits.

Note 2. The number of extended bits during addition differs depending on the addition count.

2-bit extension: 1-time to 4-time conversion (addition zero to three times)

4-bit extension: 16-time conversion (addition 15 times)

Note 3. See section 11, Low Power Consumption for details.

Note 4. Wait for 1 μs or longer to start A/D conversion after release from the module stop state.

Interrupt sources

 In the modes except double trigger mode and group scan mode, A/D scan end interrupt request

(S12ADI0) can be generated on completion of single scan.

 In double trigger mode, A/D scan end interrupt request (S12ADI0) can be generated on completion of

double scan.

 In group scan mode, an A/D scan end interrupt request (S12ADI0) can be generated on completion of

group A scan, whereas an A/D scan end interrupt request (GBADI) for group B can be generated on

completion of group B scan.

 When double trigger mode is selected in group scan mode, A/D scan end interrupt request (S12ADI0)

can be generated on completion of double scan of group A, whereas A/D scan end interrupt request

(GBADI) specially for group B can be generated on completion of group B scan.

 The S12ADI0 and GBADI interrupts can activate the DMA controller (DMAC) and the data transfer

controller (DTC).

Event link function

 An ELC event is generated on completion of scans other than group B scan in group scan mode.

 An ELC event is generated on completion of group B scan in group scan mode.

 An ELC event is generated on completion of all scans.

 Scan can be started by a trigger output by the ELC.

 An ELC event is generated according to the event conditions of the window compare function in single

scan mode.

Low power consumption

function

 Module stop state can be set.*
