CNTERR: Count Error Status Flag bit
1 = Position count error has occurred
0 = No position count error has occurred
(CNTERR flag only applies when QEIM<2:0> = ‘110’ or ‘100’)
Unimplemented: Read as ‘0’
QEISIDL: Stop in Idle Mode bit
1 = Discontinue module operation when device enters Idle mode
0 = Continue module operation in Idle mode
INDEX: Index Pin State Status bit (Read-Only)
1 = Index pin is High
0 = Index pin is Low
UPDN: Position Counter Direction Status bit
1 = Position Counter Direction is positive (+)
0 = Position Counter Direction is negative (-)
(Read-only bit when QEIM<2:0> = ‘1XX’)
(Read/Write bit when QEIM<2:0> = ‘001’)
QEIM<2:0>: Quadrature Encoder Interface Mode Select bits
111 = Quadrature Encoder Interface enabled (x4 mode) with position counter reset by match (MAXCNT)
110 = Quadrature Encoder Interface enabled (x4 mode) with Index Pulse reset of position counter
101 = Quadrature Encoder Interface enabled (x2 mode) with position counter reset by match (MAXCNT)
100 = Quadrature Encoder Interface enabled (x2 mode) with Index Pulse reset of position counter
011 = Unused (Module disabled)
010 = Unused (Module disabled)
001 = Starts 16-bit Timer
000 = Quadrature Encoder Interface/Timer off
SWPAB: Phase A and Phase B Input Swap Select bit
1 = Phase A and Phase B inputs swapped
0 = Phase A and Phase B inputs not swapped
PCDOUT: Position Counter Direction State Output Enable bit
1 = Position Counter Direction Status Output Enable (QEI logic controls state of I/O pin)
0 = Position Counter Direction Status Output Disabled (Normal I/O pin operation)
TQGATE: Timer Gated Time Accumulation Enable bit
1 = Timer gated time accumulation enabled
0 = Timer gated time accumulation disabled
