Once this timer is activated, it will give interrupts after its time-out period (see below). These interrupts continue periodically until
the interrupt is disabled. Whenever the interrupt is disabled, the wake-up timer is reset, so that a subsequent enable always results
in a full wake-up time.
The wake-up timer can be adjusted by the user through the Wake-up Timer Adjust bits in the Clock Configuration Register (Figure
9-2). These bits clear on reset. In addition to allowing the user to select a range for the wake-up time, a firmware algorithm can
be used to tune out initial process and operating condition variations in this wake-up time. This can be done by timing the wake-up
interrupt time with the accurate 1.024-ms timer interrupt, and adjusting the Timer Adjust bits accordingly to approximate the
desired wake-up time.

General Purpose I/O Ports
Ports 0 and 1 provide up to 16 versatile GPIO pins that can be read or written (the number of pins depends on package type).
Each pin can be configured as high-impedance inputs, inputs with internal pull-ups, open drain outputs, or traditional CMOS
outputs with selectable drive strengths. Figure 12-1 shows a diagram of a GPIO port pin. Each I/O pin can be configured
independently of any other pin. Port 0 is an 8-bit port; Port 1 contains either 2 bits, P1.1–P1.0 in the CY7C63722/23, or all 8-bits,
P1.7 - P1.0 in the CY7C63742/43 parts. Each bit can also be selected as an interrupt source for the microcontroller, as explained
in Section 21.3.6.
