Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 15 TON: Timer2 On bit
When T32 =
1:
1 = Starts 32-bit Timer2/3
0 = Stops 32-bit Timer2/3
When T32 =
0:
1 = Starts 16-bit Timer2
0 = Stops 16-bit Timer2
bit 14 Unimplemented: Read as ‘0’
bit 13 TSIDL: Timer2 Stop in Idle Mode bit
1 = Discontinues module operation when device enters Idle mode
0 = Continues module operation in Idle mode
bit 12-7 Unimplemented: Read as ‘0’
bit 6 TGATE: Timer2 Gated Time Accumulation Enable bit
When TCS =
1:
This bit is ignored.
When TCS = 0:
1 = Gated time accumulation is enabled
0 = Gated time accumulation is disabled
bit 5-4 TCKPS<1:0>: Timer2 Input Clock Prescale Select bits
11 = 1:256
10 = 1:64
01 = 1:8
00 = 1:1
bit 3 T32: 32-Bit Timer Mode Select bit
1 = Timer2 and Timer3 form a single 32-bit timer
0 = Timer2 and Timer3 act as two 16-bit timers
bit 2 Unimplemented: Read as ‘0’
bit 1 TCS: Timer2 Clock Source Select bit
1 = External clock from pin, T2CK (on the rising edge)
0 = Internal clock (F
CY)
bit 0 Unimplemented: Read as ‘0’
