SMOD=Serial Port Mode

Answer 2

SFR : Special Function Register
A: Accumulator(ACC)
B : B register
SP: Stack Pointer
DPTR : Data Pointer
PC: Program Counter
PSW: Program Status Word
-CY Carry flag
-AC Auxiliary Carry flag
-F0 Flag 0
-RSx Register bank select bit x
-OV Overflow flag
-P Parity flag
TMOD : Timer/Counter Mode Control Register
TCON : Timer/Counter Control Register
-TFx Timer x overflow Flag
-TRx Timer x Run control bit
-IEx Interrupt x flag
-ITx Interrupt x Type control bit
IE: Interrupt Enable Register
-EA Global disable bit
-ETx Timer x interrupt enable bit
-ES Serial Port interrupt enable bit
-EXx External interrupt x enable bit
IP: IP: Interrupt Priority Register
-PS Serial Port interrupt priority bit
-PTx Timer x interrupt priority bit.
-PXx External interrupt x priority bit.
PCON: Power Control Register
-SMOD 查的文件中沒有提到SMOD是什麼的縮寫,只提到:
SMOD1 Double Baud rate bit. When set to a 1 and Timer 1 is used to generate baud rates, and the
Serial Port is used in modes 1, 2, or 3.
SMOD0 When set, Read/Write accesses to SCON.7 are to the FE bit. When clear, Read/Write
accesses to SCON.7 are to the SM0 bit.
但在 http://acronyms.thefreedictionary.com/smod 中說SMOD是Serial Port Mode,可是在intel文件中是說SMx(x=0,1)是Serial Port Mode Bit x所以我想SMOD或SM兩者都是由Serial Port Mode的Serial和Mode兩字而來
- GFx General-purpose flag bit
-PD Power Down bit
-IDL Idle mode bit
THx: Timer x High byte
TLx: Timer x Low byte
(Timer x consists of two 8-bit registers, THx and TLx)
