Dual UART with I2C-bus/SPI interface, 64-byte FIFOs, IrDA SIR

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 4.

Table 4 summarizes the state of register after reset.

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.

Table 5 summarizes the state of output signals after reset.
