14 For the Ingenic SoCs, pin control is tightly 14 For the Ingenic SoCs, pin control is tightly bound with GPIO ports. All pins
15 may be used as GPIOs, multiplexed device fun 15 may be used as GPIOs, multiplexed device functions are configured within the
16 GPIO port configuration registers and it is 16 GPIO port configuration registers and it is typical to refer to pins using the
17 naming scheme "PxN" where x is a character i 17 naming scheme "PxN" where x is a character identifying the GPIO port with
18 which the pin is associated and N is an inte 18 which the pin is associated and N is an integer from 0 to 31 identifying the
19 pin within that GPIO port. For example PA0 i 19 pin within that GPIO port. For example PA0 is the first pin in GPIO port A,
20 and PB31 is the last pin in GPIO port B. The 20 and PB31 is the last pin in GPIO port B. The JZ4730, the JZ4740, the JZ4725B,
