Monitor Watch Dog Timer M
Load Enable
0 to 1 transition loads the
Timer M from the Timer M
latches
PHI2 System Timing Clock Select
0 = PHI2 clock source is CLK (Clock)
1 = PHI2 clock source is FCLK (Fast
Clock)
FCLK Start and Stop Control
0 = Stop FCLK
1 = Start FCLK
Timer A Enable
0 = TA clock disabled (counter stopped)
1 = TA clock enabled. This bit should be set to a 1 for UART
operation
Timer A Clock Select
0 = Timer A counts PHI2 clock pulses
1 = Timer A counts TIN negative pulses. When ACSR5=1, Timer A and RXD
are used for the UART and this bit should be cleared to "0".
Timer A Output Enable
0 = Timer A output disabled
1 = Timer A TOUT enabled. When ACSR0=1, Timer A and TXD are used for the UART.
Timer A Interrupt Enable
0 = Timer A Interrupt Disabled.
1 = Timer A Interrupt Enabled.
Timer A Edge Interrupt Flag
0 = Timer A Edge Interrupt has not occurred. This bit cannot be set when UART is in operation.
1 = Timer A edge Interrupt has occurred. This interrupt vector is located at the Asynchronous Transmitter vector
location. This bit is cleared to a "0" by writing a "1" to it. Writing a "0" to this bit has no affect.
