If an interrupt occurs when the interrupt vector is assigned to the flash memory area (SYSCR3<RVCTR> =
"0" is effective), FSTB is automatically initialized to "0", and then the interrupt vector of the flash memory
area is read. If an interrupt occurs when the interrupt vector is assigned to the RAM area (SYSCR3<RVCTR>
= "1" is effective), FSTB is not cleared to "0", and then the interrupt vector of the RAM area is read. In this
case, the RAM area should be designated as a referential address of interrupt vector. If the flash memory area is
designated as a referential address of interrupt vector, a flash standby reset occurs after an interrupt is gener-
ated.
21.2.6 Port input control register (SPCR<PIN0, PIN1>)
In serial PROM mode, the input levels of all ports, except the ports RXD0 and TXD0 used in serial PROM
mode, are physically fixed after a reset is released. This is designed to prevent a penetration current from flow-
ing through unused ports (port inputs and functional peripheral inputs, which are also used as ports, are dis-
abled). To access the flash memory using the RAM loader mode and a method other than the UART, therefore,
port inputs must be set to "enable". To enable the SCLK0 port input, set SPCR<PIN0> to "1". To enable port
inputs other than RXD0, TXD0 and SCLK0 port inputs, set SPCR<PIN1> to "1".
In MCU mode, the SPCR register does not function.
