this bit is cleared, it prevents software from setting the XT/RG bit to enable CPU operation
from crystal oscillator.
SPTA1: Serial Port 1 Transmit Activity. This bit is set during serial port 1 is currently transmitting data.
It is cleared when TI_1 bit is set by hardware. Changing the Clock Divide Control bits
CD0,CD1 will be ignored when this bit is set to 1 and SWB = 1.
SPRA1:Serial Port 1 Receive Activity. This bit is set during serial port 1 is currently receiving a data.
It is cleared when RI_1 bit is set by hardware. Changing the Clock Divide Control bits
CD0,CD1 will be ignored when this bit is set to 1 and SWB = 1.
SPTA0: Serial Port 0 Transmit Activity. This bit is set during serial port 0 is currently transmitting data.
It is cleared when TI bit is set by hardware. Changing the Clock Divide Control bits CD0,CD1
will be ignored when this bit is set to 1 and SWB = 1.
SPRA0:Serial Port 0 Receive Activity. This bit is set during serial port 0 is currently receiving a data.
It is cleared when RI bit is set by hardware. Changing the Clock Divide Control bits CD0,CD1
will be ignored when this bit is set to 1 and SWB = 1.

Mnemonic: TA
Address: C7h
TA:
The Timed Access register controls the access to protected bits. To access protected bits, the
user must first write AAH to the TA. This must be immediately followed by a write of 55H to
TA. Now a window is opened in the protected bits for three machine cycles, during which the
user can write to these bits.

Timer 2 overflow flag: This bit is set when Timer 2 overflows. It is also set when the count is
equal to the capture register in down count mode. It can be set only if RCLK and TCLK are
both 0. It is cleared only by software. Software can also set or clear this bit.
EXF2: Timer 2 External Flag: A negative transition on the T2EX pin (P1.1) or timer 2 overflow will
cause this flag to set based on the CP/RL2, EXEN2 and DCEN bits. If set by a negative
ransition, this flag must be cleared by software. Setting this bit in software or detection of a
negative transition on T2EX pin will force a timer interrupt if enabled.
RCLK: Receive Clock Flag: This bit determines the serial port 0 time-base when receiving data in
serial modes 1 or 3. If it is 0, then timer 1 overflow is used for baud rate generation, otherwise
imer 2 overflow is used. Setting this bit forces timer 2 in baud rate generator mode.
TCLK: Transmit Clock Flag: This bit determines the serial port 0 time-base when transmitting data in
modes 1 and 3. If it is set to 0, the timer 1 overflow is used to generate the baud rate clock,
otherwise timer 2 overflow is used. Setting this bit forces timer 2 in baud rate generator
mode.
EXEN2: Timer 2 External Enable. This bit enables the capture/reload function on the T2EX pin if
Timer 2 is not generating baud clocks for the serial port. If this bit is 0, then the T2EX pin will
