RA000
Port input control register (this register works only in serial PROM mode)
(0x0FD3)
SPCR
Note 1: A read or write can be performed on the SPCR register only in serial PROM mode. If a write is performed on this register
Note 2: All I/O ports are controlled by PIN0, except the ports RXD0, TXD0 and SCLK0 which are used in serial PROM mode. By
Read/Write
Bit Symbol
After reset
in MCU mode, the port input control does not function. If a read is performed on the SPCR register in MCU mode, "0" is
read from bits 7 through 0.
using PIN1, the SCLK0 pin can be configured separately from other pins.
