... The CY7C63612/13 are offered with two EPROM options to maximize flexibility and minimize cost. The CY7C63612 has 6 Kbytes of EPROM. The CY7C63613 has 8 Kbytes of EPROM. These parts include power-on reset logic, a watch dog timer, a vectored interrupt controller, and a 12-bit free-running timer. The Power-On Reset (POR) logic detects when power is applied to the device, resets the logic to a known state, and begins executing instructions at EPROM address 0x0000h ...

The program counter is cleared during reset, such that the first instruction executed after a reset is at address 0x0000h ...

The second byte is stored in memory addressed by the program stack pointer and the PSP is incremented again. The net effect is to store the program counter and flags on the program “stack” and increment the program stack ...

Data Memory Organization The CY7C63612/13 microcontrollers provide 256 bytes of data RAM. In normal usage, the SRAM is partitioned into four areas: program stack, data stack, user variables and USB endpoint FIFOs as shown below: after reset 8-bit PSP ...

I/O Register Summary I/O registers are accessed via the I/O Read (IORD) and I/O Write (IOWR, IOWX) instructions. IORD reads the selected port into the accumulator. IOWR writes data from the accumulator to the selected port. Indexed I/O Write ...

Watch Dog Reset (WDR) The Watch Dog Timer Reset (WDR) occurs when the Most Significant Bit (MSB) of the 2-bit Watch Dog Timer Register transitions from LOW to HIGH. In addition to the normal reset initialization noted under “Reset,” ...

GPIO port is configured for CMOS outputs and the output data bit is written as a “1”. Q2 and Q3 are sized to sink and source, respectively, roughly the same amount of current to ...

GPIO Configuration Port Every GPIO port can be programmed as inputs with internal pull-ups, open drain outputs, and traditional CMOS outputs. In ad- dition, the interrupt polarity for each port can be programmed. With positive interrupt polarity, a rising ...

USB Enumeration The enumeration sequence is shown below: 1. The host computer sends a Setup packet followed by a Data packet to USB address 0 requesting the Device descriptor. 2. The USB Controller decodes the request and retrieves its ...

The ‘set-up’ PID status (bit[7]) is forced HIGH from the start of the data packet phase of the set-up transaction, until the start of the ACK packet returned by the SIE. The CPU is prevented from clearing this bit during ...

Timer Interrupt There are two timer interrupts: the 128- s interrupt and the 1.024-ms interrupt. The user should disable both timer interrupts before going into the suspend mode to avoid possible conflicts between servicing the interrupts first or the ...

The ‘In’ column represents the SIE’s response to the token type. A disabled endpoint will remain such until firmware changes it, and all endpoints reset to disabled. Any Setup packet to an enabled and accepting endpoint will be changed by ...
