7.4 Hardware Reset, Power-On Reset (POR) and Software Reset
These three reset methods are identical and will reset the internal registers as indicated in
Table
Table 4
Table 4.
Remark: Registers DLL, DLH, SPR, XON1, XON2, XOFF1, XOFF2 are not reset by the
top-level reset signal RESET, POR and Software Reset, that is, they hold their
initialization values during reset.
