38 / 136 page  Obsolete Product(s) - Obsolete Product(s) Obsolete Product(s) - Obsolete Product(s) Supply, reset and clock management ST7LITEUS2, ST7LITEUS5 38/136 This 16-bit register is read/write by software but can be written only once between two reset events. It is cleared by hardware after a reset; When both MUXCR0 and MUXCR1 registers are at 00h, the multiplexed PA3/RESET pin will act as RESET. To configure this pin as output (Port A3), write 55h to MUXCR0 and AAh to MUXCR1. These registers are one-time writable only. ● To configure PA3 as general purpose output: After power-on / reset, the application program has to configure the I/O port by writing to these registers as described above. Once the pin is configured as an I/O output, it cannot be changed back to a reset pin by the application code. ● To configure PA3 as RESET: An internally generated reset (such as POR, LVD, WDG, illegal opcode) will clear the two registers and the pin will act again as a reset function. Otherwise, a power-down is required to put the pin back in reset configuration. Table 8. Multiplexed IO register map and reset values Address (Hex.)
