ST92163 - USB PERIPHERAL (USB)
USB INTERFACE (
Cont’d
)
DEVICE n ADDRESS (DADDRn)
R240 to R247 - Read/Write
Register page: 15
Reset Value: 0000 0000 (00h)
Note:
This register is also reset when a USB reset
is received from the USB bus or forced through bit
FRES in the USBCTLR register.
Bit 7 =
EF
: Enable Function
Set by software to enable the USB function whose
address is contained in the following ADD[6:0]
bits.
0: Function disabled
1: Function enabled
Bits 6:0 =
ADD[6:0]
: Device Address
Software mustwrite into these bits the USB device
address assigned by the host PC during the enu-
meration.
ENDPOINT n REGISTER A (EPnRA)
(TRANSMISSION)
R240-R254 (even)
Read/Write
Register pages: 4 & 5
Reset value: 0000 0000 (00h)
These registersare used for controlling data trans-
mission. They are also reset when a USB reset is
received or forced through the FRES bit in the US-
BCTLR register.
Note:
The CTR bits are not affected by a USB re-
set
Each endpoint has its EPnRA register where n is
the endpoint identifier in the range 0 to 15.
Bit 7 =
CTR
: Correct Transfer
Set by hardware when a transaction issuccessful-
ly completed on this endpoint; software can only
clear this bit.
0: No correct transfer occured
1: Correct transfer occured
Note:
A transaction ended with a NAK or STALL
handshake does not set this bit, since no data is
actually transferred, as in the case of protocol er-
rors or data toggle mismatches. The CTR bit is
also used to perform flow control: while CTR=1, a
valid endpoint answers NAK to every transaction
addressed to it (except SETUP requestswhich are
simply ignored) until the application software ac-
knowledges the CTR event, resetting this bit. This
does not apply to isochronous endpoints whereno
handshake phase is used.
Bit 6 =
DTOG_TX
: Data Toggle, for transmission
transfers
If the endpoint isnon-isochronous, this bit contains
the
required
value
of
(0=DATA0, 1=DATA1) for the next data packet to
be transmitted. Hardware togglesthis bit when the
ACK handshake is received from the USB host,
following a data packet transmission. If the end-
point is defined as a control one, hardware sets
this bit to 1 on reception of a SETUP PID ad-
dressed to this endpoint.
If the endpoint is isochronous, this bit is used to
support DMA buffer swapping since no data tog-
gling is used for this sort of endpoint and only
DATA0 packet are transmitted. Hardware toggles
this bit just after the end of data packet transmis-
sion, since no handshake is used for isochronous
transfers.
Note:
this bit can be also written by software to in-
itialize it (mandatory when the endpoint is not a
control endpoint) or to force specific data toggle/
DMA buffer usage.
