Chapter 12 Serial Port (SIO)
12 – 3
OPTION B (D): 1.5 V (3.0 V), With regulator
circuit for LCD bias
OPTION A (C): 1.5 V (3.0 V), Without regulator
circuit for LCD bias

Serial Port Registers
(1) Send control registers 0/1 (STCON0, STCON1)
STCON0 and STCON1 are 4-bit special function registers (SFRs) to control the serial port send operation.
STCON0 and STCON1 are initialized to “0” at system reset.
bit 3: STSTB (Serial Transmission STop Bit)
This bit specifies stop bit length. Valid only when bit 0 is “0” (UART mode).
bit 2, 1: STL1 (Serial Transmission Length select bit 1),
STL0 (Serial Transmission Length select bit 0)
These bits specify the send data length.
bit 0: STMOD (Serial Transmission MODe bit)
This bit specifies the serial port send operation mode.
