General PWM Timer Buffer Enable Register
| BD | BD[3]: GTDV Buffer Operation DisableBD[2]: GTADTR Buffer Operation DisableBD[1]: GTPR Buffer Operation DisableBD[0]: GTCCR Buffer Operation Disable 0 (0): Enable buffer operation 1 (1): Disable buffer operation |
| CCRA | GTCCRA Buffer Operation 0 (00): Buffer operation is not performed 1 (01): Single buffer operation (GTCCRA <–> GTCCRC) 2 (10): Double buffer operation (GTCCRA <–> GTCCRC <–> GTCCRD) 3 (11): Double buffer operation (GTCCRA <–> GTCCRC <–> GTCCRD) |
| CCRB | GTCCRB Buffer Operation 0 (00): Buffer operation is not performed 1 (01): Single buffer operation (GTCCRB <–> GTCCRE) 2 (10): Double buffer operation (GTCCRB <–> GTCCRE <–> GTCCRF) 3 (11): Double buffer operation (GTCCRB <–> GTCCRE <–> GTCCRF) |
| PR | GTPR Buffer Operation 0 (00): Buffer operation is not performed 1 (01): Single buffer operation (GTPBR --> GTPR) 2 (10): Double buffer operation (GTPDBR --> GTPBR --> GTPR) 3 (11): Double buffer operation (GTPDBR --> GTPBR --> GTPR) |
| CCRSWT | GTCCRA and GTCCRB Forcible Buffer OperationThis bit is read as 0. 0 (0): no effect 1 (1): Forcibly performs buffer transfer of GTCCRA and GTCCRB. This bit automatically returns to 0 after the writing of 1. |
| ADTTA | GTADTRA Buffer Transfer Timing Select in the Triangle wavesNOTE: In the Saw waves, values other than 0 0: Transfer at an underflow (in down-counting) or overflow (in up-counting) is performed. 0 (00): No transfer 1 (01): Transfer at crest 2 (10): Transfer at trough 3 (11): Transfer at both crest and trough |
| ADTDA | GTADTRA Double Buffer Operation 0 (0): Single buffer operation (GTADTBRA --> GTADTRA) 1 (1): Double buffer operation (GTADTDBRA --> GTADTBRA --> GTADTDRA) |
| ADTTB | GTADTRB Buffer Transfer Timing Select in the Triangle wavesNOTE: In the Saw waves, values other than 0 0: Transfer at an underflow (in down-counting) or overflow (in up-counting) is performed. 0 (00): No transfer 1 (01): Transfer at crest 2 (10): Transfer at trough 3 (11): Transfer at both crest and trough |
| ADTDB | GTADTRB Double Buffer Operation 0 (0): Single buffer operation (GTADTBRB --> GTADTRB) 1 (1): Double buffer operation (GTADTDBRB --> GTADTBRB --> GTADTDRB) |
