The SPI Master/Slave Interface core logic runs on the SPI
clock domain, making its functionality independent of system
clock speed. SPI is a four pin serial interface comprised of a
clock, an enable and two data pins.

Table 15-1. SPI Data Register (SPIDATA) [0x3C] [R/W]
When an interrupt occurs to indicate to firmware that a byte of
receive data is available, or the transmitter holding register is
empty, firmware has 7 SPI clocks to manage the buffers—to
This register exists in CY7C638xx and CY7C639xx. In CY7C638xx this register controls the operation of pins P3.0–P3.1. In the
CY7C639xx, this register controls the operation of pins P3.0–P3.7
The 50-mA sink drive capability is only available on pin P3.7 and only on the CY7C639xx. In the CY7C638xx, only 8-mA sink
drive capability is available on this pin regardless of the setting of the High Sink bit
This register exists only in the CY7C639xx. This register controls the operation of pins P4.0–P4.3
When read, this register returns the contents of the receive buffer. When written, it loads the transmit holding register
