16.3.1
Port E is a 16-bit input/output port in the SH7125 and a 12-bit input/output port in the SH7124.
Port E has the following registers. For details on register addresses and register states during each
processing, refer to section 20, List of Registers.
Table 16.5 Register Configuration
16.3.2
PEDRL is a 16-bit readable/writable register that stores port E data. Bits PE15DR to PE0DR
correspond to pins PE15 to PE0 (multiplexed functions omitted here) in the SH7125. Bits
PE15DR to PE8DR and PE3DR to PE0DR correspond to pins PE15 to PE8 and PE3 to PE0,
respectively (multiplexed functions omitted here) in the SH7124.
When a pin function is general output, if a value is written to PEDRL, that value is output directly
from the pin, and if PEDRL is read, the register value is returned directly regardless of the pin
state.
When a pin function is general input, if PEDRL is read, the pin state, not the register value, is
returned directly. If a value is written to PEDRL, although that value is written into PEDRL, it
does not affect the pin state. Table 16.6 summarizes port E data register read/write operations.
