24.13 Cautions
1548
(1) Caution for VSWC register
(2) Caution for reading DCHCn.TCn bit (n = 0 to 3)
When using the DMAC, be sure to set an appropriate value, in accordance with the operating frequency, to the
VSWC register.
When the default value (77H) of the VSWC register is used, or if an inappropriate value is set to the VSWC
register, the operation is not correctly performed (for details of the VSWC register, see 3.4.9 (1) (a) System
wait control register (VSWC)).
The TCn bit is cleared to 0 when it is read, but it is not automatically cleared even if it is read at a specific
timing. To accurately clear the TCn bit, add the following processing.
(a) When waiting for completion of DMA transfer by polling TCn bit
(b) When reading TCn bit in interrupt servicing routine
Confirm that the TCn bit has been set to 1 (after TCn bit = 1 is read), and then read the TCn bit three more
times.
Execute reading the TCn bit three times.
