Section 8 Data Transfer Controller (DTC)
Table 8.10 Number of Cycles Required for Each Execution State
[Legend]
m: Number of wait cycles 0 to 7 (For details, see section 6, Bus Controller (BSC).)
The number of execution cycles is calculated from the formula below. Note that Σ means the sum
of all transfers activated by one activation event (the number in which the CHNE bit is set to 1,
plus 1).
8.5.10
The DTC requests the bus mastership to the bus arbiter when an activation request occurs. The
DTC releases the bus after a vector read, transfer information read, a single data transfer, or
transfer information writeback. The DTC does not release the bus during transfer information
read, single data transfer, or transfer information writeback.
8.5.11
The priority of the DTC activation sources over the CPU can be controlled by the CPU priority
level specified by bits CPUP2 to CPUP0 in CPUPCR and the DTC priority level specified by bits
DTCP2 to DTCP0. For details, see section 5, Interrupt Controller.
