Table 14-17. P3 Configuration (P3CR) [0x16] [R/W]
15. Serial Peripheral Interface (SPI)
The SPI Master/Slave Interface core logic runs on the SPI clock domain, so that its functionality is independent of system clock speed.
SPI is a four pin serial interface comprised of a clock, an enable and two data pins.
15.1 SPI Data Register
Table 15-1. SPI Data Register (SPIDATA) [0x3C] [R/W]
When an interrupt occurs to indicate to the firmware that a byte of receive data is available, or the transmitter holding register is empty,
the firmware has 7 SPI clocks to manage the buffers: to empty the receiver buffer or to refill the transmit holding register. Failure to
meet this timing requirement results in incorrect data transfer.
Document 38-08035 Rev. *K
This register exists in CY7C638(2/3)3. This register controls the operation of pins P3.0–P3.1.
When read, this register returns the contents of the receive buffer. When written, it loads the transmit holding register.
