bit 4-3
bit 2
bit 1
bit 0
TQCKPS<1:0>: Timer Input Clock Prescale Select bits
11 = 1:256 prescale value
10 = 1:64 prescale value
01 = 1:8 prescale value
00 = 1:1 prescale value
(Prescaler utilized for 16-bit Timer mode only)
POSRES: Position Counter Reset Enable bit
1 = Index Pulse resets Position Counter
0 = Index Pulse does not reset Position Counter
TQCS: Timer Clock Source Select bit
1 = External clock from pin QEA (on the rising edge)
0 = Internal clock (TCY)
UPDN_SRC: Position Counter Direction Selection Control bit
1 = QEB pin state defines position counter direction
0 = Control/Status bit, UPDN (QEICON<11>), defines timer counter (POSCNT) direction
Note:
Note:
QEICON: QEI CONTROL REGISTER (CONTINUED)
Bit applies only when QEIM<2:0> = 100 or 110.
When configured for QEI mode, control bit is a ‘don’t care’.
