mode, are physically fixed after a reset is released. This is designed to prevent a penetration current from flowing
through unused ports (port inputs and functional peripheral inputs, which are also used as ports, are disabled).
inputs must be set to "enable". To enable the SCLK0 port input, set SPCR<PIN1> to "1". To enable port inputs
other than RXD0, TXD0 and SCLK0 port inputs, set SPCR<PIN0> to "1".
In serial PROM mode, the input levels of all ports, except the ports RXD0 and TXD0 used in serial PROM
To access the flash memory using the RAM loader mode and a method other than the UART, therefore, port
In MCU mode, the SPCR register does not function.
