This register controls the operation of the P1.3 pin. This register exists in all enCoRe II parts
The P1.3 GPIO’s threshold is always set to TTL
When the SPI hardware is enabled, the output enable and output state of the pin is controlled by the SPI circuitry. When the SPI
hardware is disabled, the pin is controlled by the Output Enable bit and the corresponding bit in the P1 data register.
Regardless of whether the pin is used as an SPI or GPIO pin the Int Enable, Int act Low, 3.3V Drive, High Sink, Open Drain, and
Pull-up Enable control the behavior of the pin
The 50 mA sink drive capability is only available in the CY7C638xx.

These registers control the operation of pins P1.4–P1.6, respectively. These registers exist in all enCoRe II parts
The P1.4–P1.6 GPIO’s threshold is always set to TTL
When the SPI hardware is enabled, pins that are configured as SPI Use have their output enable and output state controlled by
the SPI circuitry. When the SPI hardware is disabled or a pin has its SPI Use bit clear, the pin is controlled by the Output Enable
bit and the corresponding bit in the P1 data register.
Regardless of whether any pin is used as an SPI or GPIO pin the Int Enable, Int act Low, 3.3V Drive, High Sink, Open Drain,
and Pull-up Enable control the behavior of the pin
The 50 mA sink drive capability is only available in the CY7C638xx.
Bit 7:
SPI Use
0 = Disable the SPI alternate function. The pin is used as a GPIO
1 = Enable the SPI function. The SPI circuitry controls the output of the pin
Important Note for Comm Modes 01 or 10 (SPI Master or SPI Slave, see
Table 15-2
):
When configured for SPI (SPI Use = 1 and Comm Modes [1:0] = SPI Master or SPI Slave mode), the input/output direction of
pins P1.3, P1.5, and P1.6 is set automatically by the SPI logic. However, pin P1.4's input/output direction is NOT automatically
set; it must be explicitly set by firmware. For SPI Master mode, pin P1.4 must be configured as an output; for SPI Slave mode,
pin P1.4 must be configured as an input.
