USB INTERFACE
(Cont’d)
DEVICE ADDRESS REGISTER (DADDR)
Read/Write
Reset Value: 0000 0000 (00h)
Bit 7 = Reserved, forced by hardware to 0.
Bits 6:0 =
ADD[6:0]
Device address, 7 bits.
Software must write into this register the address
sent by the host during enumeration.
Note:
This register is also reset when a USB reset
is received or forced through bit FRES in the US-
BCTLR register.
USB STATUS REGISTER (USBSR)
Read only
Reset Value: 0000 0000 (00h)
Bits 7:6 =
PID[1:0]
Token PID bits 1 & 0 for End-
point 0 Control
.
USB token PIDs are encoded in four bits. PID[1:0]
correspond to the most significant bits of the PID
field of the last token PID received by Endpoint 0.
Note:
The least significant PID bits have a fixed
value of 01.
When a CTR interrupt occurs on Endpoint 0 (see
register USBISTR) the software should read the
PID[1:0] bits to retrieve the PID name of the token
received.
The USB specification defines PID bits as:
Bit 5 =
IN/OUT
Last transaction direction for End-
point 1, 2 , 3, 4 or 5.
This bit is set by hardware when a CTR interrupt
occurs on Endpoint 1, 2, 3, 4 or 5.
0: OUT transaction
1: IN transaction
Bits 4:3 = Reserved, forced by hardware to 0.
Bits 2:0 =
EP[2:0]
Endpoint number.
These bits identify the endpoint which required at-
tention.
000 = Endpoint 0
001 = Endpoint 1
010 = Endpoint 2
011 = Endpoint 3
100 = Endpoint 4
101 = Endpoint 5
ERROR STATUS REGISTER (ERRSR)
Read only
Reset Value: 0000 0000 (00h)
Bits 7:3 = Reserved, forced by hardware to 0.
Bits 2:0 =
ERR[2:0]
Error type
.
These bits identify the type of error which oc-
curred.
Note:
these bits are set by hardware when an er-
ror interrupt occurs and are reset automatically
when the error bit (USBISTR bit 4) is cleared by
software.
