Reset

Table 7 summarizes the state of outputs after reset.

Table 7. Register Reset Functions(1)

REGISTER NAME RESET CONTROL RESET STATE
IER Interrupt enable register RESET 0x00
IIR Interrupt identification register RESET 0x01
FCR FIFO control register RESET 0x00
LCR Line control register RESET 0x1D
MCR Modem control register RESET 0x00
LSR Line status register RESET 0x60
MSR Modem status register RESET Bits 0 to 3 cleared. Bits 4 to 7 input signals.
EFR Enhanced feature register RESET 0x00
RHR Receiver holding register RESET Pointer logic cleared
THR Transmitter holding register RESET Pointer logic cleared
TCR Transmission control register RESET 0x00
TLR Trigger level register RESET 0x00
AFR Alternate function register RESET 0x10
Registers DLL, DLH, SPR, Xon1, Xon2, Xoff1, and Xoff2 are not reset by the top-level reset signal RESET, that is, they hold their initialization values during reset.

Table 8 summarizes the state of outputs after reset.
