Low-Power, Dual-Core Microcontroller
Timer 2 Output Enable 0. This register bit enables the timer 2 output function for the external T2P
pin. The table below shows timer 2 output possibilities for the T2, T2PB pins.
Enable Timer 2 Interrupts. This bit serves as the local enable for timer 2 interrupt sources that fall
under the TF2 and TCC2 interrupt flags.
Timer 2 Most Significant Byte
The timer 2 most significant byte is cleared to 00h on all forms of reset.
Unrestricted read/write.
Timer 2 MSB Bits 7:0. This register is used to load and read the most significant 8-bit value in timer 2.
Timer 2 Most Significant Byte Reload
The timer 2 most significant byte is cleared to 00h on all forms of reset.
Unrestricted read/write.
Timer 2 Reload MSB Bits 7:0. This register is used to load and read the most significant 8-bit
value in timer 2.
Timer 2 Most Significant Byte Capture/Compare
This byte is cleared to 00h on all forms of reset.
Unrestricted read/write.
Timer 2 Capture/Compare MSB Bits 7:0. This register reflects the upper byte of the timer 2
capture/compare value and is read/write accessible at all times.
Port 2 Output Register (8-Bit Register)
This register is set to 1Fh on all forms of reset.
Unrestricted read/write.
Port 2 Output Register Bits 6:0. The PO2 register stores output data for port 2 when it is defined as
an output port and controls whether the internal weak p-channel pullup transistor is
enabled/disabled if a port pin is defined as an input. The contents of this register can be modified
by a write access. Reading from the register returns the contents of the register. Changing the
direction of port 2 does not change the data contents of the register.
Reserved. Reads return 0.
