Bit
Description
15 to 9
Reserved. These bits are reserved and should be written as 0 by user code.
8
Count up/count down enable.
This bit is set by user code to configure Timer2 to count up.
This bit is cleared by user code to configure Timer2 to count down.
7
Timer2 enable.
This bit is set by user code to enable Timer2.
This bit is cleared by user code to disable Timer2.
6
Timer2 operating mode.
This bit is set by user code to configure Timer2 to operate in periodic mode.
This bit is cleared by user to configure Timer2 to operate in free running mode.
5
Watchdog timer mode enable.
This bit is set by user code to enable watchdog mode.
This bit is cleared by user code to disable watchdog mode.
4
Reserved. This bit is reserved and should be written as 0 by user code.
3 to 2
Timer2 clock prescaler.
00 = source clock/1 (default).
01 = source clock/16.
10 = source clock/256.
11 = reserved.
1
Watchdog timer IRQ enable.
This bit is set by user code to produce an IRQ instead of a reset when the watchdog reaches 0.
This bit is cleared by user code to disable the IRQ option.
0
PD_OFF.
This bit is set by the user code to stop Timer2 when the peripherals are powered down using Bit 4 in the POWCON MMR.
This bit is cleared by the user code to enable Timer2 when the peripherals are powered down using Bit 4 in the
POWCON MMR.
