USBIO, D+
Provides D+ connection directly to a USB 2.0 bus. May be used
as a digital I/O pin. Pins are Do Not Use (DNU) on devices
without USB.
USBIO, D–
Provides D– connection directly to a USB 2.0 bus. May be used
as a digital I/O pin. Pins are No Connect (NC) on devices without
USB.
Vboost
Power sense connection to boost pump.
Vbat
Battery supply to boost pump.
Vcca
Output of analog core regulator and input to analog core.
Requires a 1-µF capacitor to V
external use.
Vccd
Output of digital core regulator and input to digital core. The two
V
them as short as possible, and a 1-µF capacitor to V
Power System
Vdda
Supply for all analog peripherals and analog core regulator.
Vdda must be the highest voltage present on the device. All
other supply pins must be less than or equal to V
Vddd
Supply for all digital peripherals and digital core regulator. V
must be less than or equal to V
Vssa
Ground for all analog peripherals.
Vssb
Ground connection for boost pump.
Vssd
Ground for all digital logic and I/O pins.
Vddio0, Vddio1, Vddio2, Vddio3
Supply for I/O pins. See pinouts for specific I/O pin to Vddio
mapping. Each Vddio must be tied to a valid operating voltage
(1.71 V to 5.5 V), and must be less than or equal to Vdda. If the
I/O pins associated with Vddio0, Vddio2 or Vddio3 are not used
then that Vddio should be tied to ground (Vssd or Vssa).
XRES (and configurable XRES)
External reset pin. Active low with internal pull-up. Pin P1[2] may
be configured to be a XRES pin; see

4. CPU
4.1 8051 CPU
The CY8C32 devices use a single cycle 8051 CPU, which is fully
compatible with the original MCS-51 instruction set. The
CY8C32 family uses a pipelined RISC architecture, which
executes most instructions in 1 to 2 cycles to provide peak
performance of up to 24 MIPS with an average of 2 cycles per
instruction. The single cycle 8051 CPU runs ten times faster than
a standard 8051 processor.
The 8051 CPU subsystem includes these features:
4.2 Addressing Modes
The following addressing modes are supported by the 8051:
Single cycle 8051 CPU
Up to 64 KB of flash memory, up to 2 KB of EEPROM, and up
to 8 KB of SRAM
Programmable nested vector interrupt controller
Direct memory access (DMA) controller
Peripheral HUB (PHUB)
External memory interface (EMIF)
Direct Addressing: The operand is specified by a direct 8-bit
address field. Only the internal RAM and the SFRs can be
accessed using this mode.
Indirect Addressing: The instruction specifies the register which
contains the address of the operand. The registers R0 or R1
are used to specify the 8-bit address, while the data pointer
(DPTR) register is used to specify the 16-bit address.
Register Addressing: Certain instructions access one of the
registers (R0 to R7) in the specified register bank. These
instructions are more efficient because there is no need for an
address field.
Register Specific Instructions: Some instructions are specific
to certain registers. For example, some instructions always act
on the accumulator. In this case, there is no need to specify the
operand.
Immediate Constants: Some instructions carry the value of the
constants directly instead of an address.
Indexed Addressing: This type of addressing can be used only
for a read of the program memory. This mode uses the data
pointer as the base and the accumulator value as an offset to
read a program memory.
Bit Addressing: In this mode, the operand is one of 256 bits.
