REGISTER 10-13: BUFFER DESCRIPTOR ADDRESS LOW
(BDndAL: 1A2h, 1A6h, 1AAh, 1AEh, 1B2h, 1B6h)
10.6.1
ENDPOINT BUFFERS
Endpoint buffers are located in the Dual Port RAM
area. The starting location of an endpoint buffer is
determined by the Buffer Descriptor.
10.7
Transceiver
An on-chip integrated transceiver is included to drive
the D+/D- physical layer of the USB.
10.7.1
REGULATOR
A 3.3V regulator provides the D+/D- drives with power,
as well as an external pin. This pin is intended to be
used to power a 1.5k
+5% pull-up resistor on the D-
line to signal a low speed device, as specified by the
USB 1.1 Specification. A +20% 200nF capacitor is
required on VUSB for regulator stability.

10.7.1.1
VUSB Output
The VUSB provides a 3.3V nominal output. This drive
current is sufficient for a pull-up only.
10.8
USB Software Libraries
Microchip Technology provides a comprehensive set
of Chapter 9 Standard requests functions to aid devel-
opers in implementing their designs. See Microchip
Technology’s website for the latest version of the soft-
ware libraries.

bit 7-0:
BA<7:0>: Buffer Address
The base address of the buffer controlled by this endpoint. The upper order bit address (BA8) of the
9-bit address is assumed to be 1h. This value must point to a location within the dual port memory
space, Bank 3 (1B8h - 1DFh).
Note 1: This register should always contain a value between B8h-DFh.
