D0 T8ORun: Timer Run/Stop Control Bit
Controls the timer Run/Stop.
1 (R/W): Run
0 (R/W): Stop (default)
The timer starts counting when T8ORUN is written as 1 and stops when written as 0. When the timer is
stopped, the counter data is retained until reset or until the next Run state.
T8OSC1 Counter Data Register (T8OSC1_CnT)
Register name address Bit
T8OSC1 0x50c1 D7–0 T8OCnT[7:0] Timer counter data
Counter Data (8 bits)
Register
(T8OSC1_CnT)
D[7:0] T8OCnT[7:0]: Timer Counter Data Bits
Counter data can be read out. (Default: 0x0)
This register is read-only and cannot be written to.
note: The correct counter value may not be read out (reading is unstable) if the register is read while
counting is underway.
Obtain the counter value by one of the following methods:
• Read the counter value while the counter is halted.
• Read the counter twice in succession. Treat the value as valid if the values read are identical.
T8OSC1 Compare Data Register (T8OSC1_CMP)
Register name address Bit
T8OSC1 0x50c2 D7–0 T8OCMP[7:0] Compare data
Compare Data
(8 bits)
Register
(T8OSC1_CMP)
D[7:0] T8OCMP[7:0]: Compare Data
Sets compare data. (Default: 0x0)
The data set is compared against the counter data, and a compare match interrupt cause is generated if
the contents match. And the counter is reset to 0.
T8OSC1 interrupt Mask Register (T8OSC1_iMSK)
Register name address Bit
T8OSC1 0x50c3 D7–1 –

D0
Register
(T8OSC1_iMSK)
D[7:1] Reserved
D0 T8Oie: T8OSC1 interrupt enable Bit
Enables or disables compare match interrupts.
1 (R/W): Interrupt enabled
0 (R/W): Interrupt disabled (default)
Setting T8OIE to 1 enables T8OSC1 interrupt requests to the ITC. Setting it to 0 disables interrupts.
