22.5.1
Port E is a 13-bit input/output port in the SH7083; a 16-bit input/output port in the SH7084 and
SH7085; a 22-bit input/output port in the SH7086. Port E has the following registers. For details
on register addresses and register states during each processing, refer to section 27, List of
Registers.
Table 22.9 Register Configuration
22.5.2
The port E data registers H and L (PEDRH and PEDRL) are 16-bit readable/writable registers that
store port E data. Bits PE15DR to PE12DR, PE10DR, PE8DR to PE6DR, and PE4DR to PE0DR
correspond to pins PE15 to PE12, PE10, PE8 to PE6, and PE4 to PE0, respectively (multiplexed
functions omitted here) in the SH7083. Bits PE15DR to PE0DR correspond to pins PE15 to PE0
(multiplexed functions omitted here) in the SH7084 and SH7085. Bits PE21DR to PE0DR
correspond to pins PE21 to PE0, respectively (multiplexed functions omitted here) in the SH7086.
When a pin function is general output, if a value is written to PEDRH or PEDRL, that value is
output directly from the pin, and if PEDRH or PEDRL is read, the register value is returned
directly regardless of the pin state.
When a pin function is general input, if PEDRH or PEDRL is read, the pin state, not the register
value, is returned directly. If a value is written to PEDRH or PEDRL, although that value is
written into PEDRH or PEDRL, it does not affect the pin state. Table 22.10 summarizes port E
data register read/write operations.
