CADDR
Configuration Address. This register supplies the address for reading bytes in the 128 bytes of Flash Configuration
bits 70
Memory. It is recommended that faddr_data_read be used when accessing Configuration memory.This register is
also used as the address for the sfr_read and sfr_write routines, so it must be set prior to their use.
CAUTION: If this register is written to while executing from Flash Memory, the CDATA register will be incorrect.

Serial Port 0 Mode. These bits control the mode of serial Port 0. Modes 1, 2, and 3 have 1 start and 1 stop bit in
bits 75
addition to the 8 or 9 data bits.

(1) p
CLK will be equal to tCLK, except that pCLK will stop for Idle mode.
(2) RI_0 will only be activated when a valid STOP is received.
(3) RI_0 will not be activated if bit 9 = 0.
REN_0
Receive Enable. This bit enables/disables the serial Port 0 received shift register.
bit 4
0: Serial Port 0 reception disabled.
1: Serial Port 0 received enabled (modes 1, 2, and 3). Initiate synchronous reception (mode 0).
TB8_0
9th Transmission Bit State. This bit defines the state of the 9th transmission bit in serial Port 0 modes 2 and 3.
bit 3
RB8_0
9th Received Bit State. This bit identifies the state of the 9th reception bit of received data in serial Port 0 modes
bit 2
2 and 3. In serial port mode 1, when SM2_0 = 0, RB8_0 is the state of the stop bit. RB8_0 is not used in mode 0.
TI_0
Transmitter Interrupt Flag. This bit indicates that data in the serial Port 0 buffer has been completely shifted out. In serial
bit 1
port mode 0, TI_0 is set at the end of the 8th data bit. In all other modes, this bit is set at the end of the last data bit.
This bit must be manually cleared by software.
RI_0
Receiver Interrupt Flag. This bit indicates that a byte of data has been received in the serial Port 0 buffer. In serial
bit 0
port mode 0, RI_0 is set at the end of the 8th bit. In serial port mode 1, RI_0 is set after the last sample of the incoming
stop bit subject to the state of SM2_0. In modes 2 and 3, RI_0 is set after the last sample of RB8_0. This bit must
be manually cleared by software.
