A value of 1 can always be written to the SWDTE bit, but 0 can only be written after 1 is read. 2. Only write to bits DTVEC6 to DTVEC0 when SWDTE is 0. Notes: DTC Software Activation Enable Sets vector number for DTC software activation Bit Initial value Read/Write : : : 0 1 DTC software activation is disabled [Clearing conditions] • When the DISEL bit is 0 and the specified number of transfers have not ended • When 0 is written to the DISEL bit after a software-activated data transfer end interrupt (SWDTEND) request has been sent to the CPU. DTC software activation is enabled [Holding conditions] • When the DISEL bit is 1 and data transfer has ended • When the specified number of transfers have ended • During data transfer activated by software 662 SCKCR H'FF3A Clock Pulse Generator Figure amended 7 PSTOP 0 R/W 6 — 0 R/W Bit Initial value Read/Write : : : 680 SSR0 H'FF7C SCI0 Note *2 added R/(W) *1 DTC*2 Notes: 1. Can only be written with 0 for flag clearing. 2. DTC can clear this bit only when DISEL is 0 with the transfer counter not being 0. |
