(1) EPB_RDY (Buffer Ready Interrupt) Bits (b6~b0)
The bit corresponding to each endpoint is set to “1” with the buffer at “ready” state.
The ready state refers to the state when CPU or DMAC can read or write the CPU side buffer. When the EPB_RE
bit is set to “1”, if this bit is set to “1”, the INTR bit is set to “1”, causing the buffer ready interrupt to occur.
Setting “1”/clearing to ”0” to this bit differs according to the endpoint and transfer direction as shown below:
Note :
Refer to “3.2 FIFO Buffer” for CPU/SIE side.
Endpoint 0
When set to control write transfer (ISEL bit = “0”)
The condition for this bit to be set to “1” is as follows:
When the IVAL bit of the EP0_FIFO Control Register changes from “0” to “1”
The condition for this bit to be cleared to “0” differs according to the RDYM bit:
RDYM bit = “0” : When the IVAL bit of the EP0_FIFO Control Register changes from
“1” to“0”
RDYM bit = “1” : Writes “0” to this bit
When set to control read transfer (ISEL bit = “1”)
This bit is not set to “1” (Refer to “EPB_EMP_OVR bit”).
