Table 94
Parallel Port Data Register
Note
1.
RSTx = 0 means reset condition if either RSTO or RSTC is asserted; ‘
’ denotes not affected from reset line.
During reset (RST, RSTO, RSTC) only those registers with an explicitly given reset value are affected. All other
registers are undefined and have to be set by the controller.
Table 95
Parallel Port Data Direction Register
Note
1.
RSTx = 0 means reset condition if either RSTO or RSTC is asserted; ‘
’ denotes not affected from reset line.
During reset (RST, RSTO, RSTC) only those registers with an explicitly given reset value are affected. All other
registers are undefined and have to be set by the controller.

System Configuration Register (SYSCON)
Note
1.
RSTx = 0 means reset condition if either RSTO or RSTC is asserted; ‘

During reset (RST, RSTO, RSTC) only those registers with an explicitly given reset value are affected. All other
registers are undefined and have to be set by the controller.
