Updates: product information (Figure 3, 4, Table 1, 2); port information (Figure 17, 18,
Table 30); interface information (Figure 30, Table 44); remove programming guide; PSD
Module information (Figure 50, 51, Table 85); PLD information (Figure 58, 59, Table 91,
92, 93); electrical characteristics (Table 118, 119, 135, 136)
Updated references for Product Catalog
Reformatted; corrected mechanical dimensions (Table 148)
Reformatted; added EMC characteristics (Table 109, 110, 111)
Updates according to data brief change request (Figure 3, 4; Table 1, 2, 116)
An 8-bit, Programmable PWM 4 channel
and the associated registers are added.
When DDC is disabled, the data space
FF00h-FFFFh assigned to DDC SRAM is
available for external data mapping. The
SWENB Bit definition in the DDCON
Register is modified.

Option to block USB generated reset
from resetting the MCU/PSD modules.
Allow USB Reset Flag (RSTF) to
interrupt MCU.
Add RSTE and RSTFIE Bits to the
UIEN Interrupt Enable Register.

uPSD3234A, uPSD3234BV, uPSD3233B, uPSD3233BV
Revision Details
Only PWM0-PWM3 channels are
available.
Data space FF00h-FFFFh is dedicated to
DDC SRAM.
USB-generated reset always resets both,
the USB and the MCU/PSD modules.
