SIFS2x
Bits
15-14
S2 source select. These bits select the S2 source for the PSM when SIFCS
= 1.
00 SIF0OUT is the S2 source.
01 SIF1OUT is the S2 source.
10 SIF2OUT is the S2 source.
11 SIF3OUT is the S2 source.
SIFS1x
Bits
13-12
S1 source select. These bits select the S1 source fro the PSM when SIFCS
= 1.
00 SIF0OUT is the S1 source.
01 SIF1OUT is the S1 source.
10 SIF2OUT is the S1 source.
11 SIF3OUT is the S1 source.
SIFIS2x
Bits
11-10
SIFIFG4 interrupt flag source
00 SIFIFG4 is set with each count of SIFCNT2.
01 SIFIFG4 is set if (SIFCNT2 modulo 4) = 0.
10 SIFIFG4 is set if (SIFCNT2 modulo 64) = 0.
11 SIFIFG4 is set when SIFCNT2 decrements from 01h to 00h.
SIFIS1x
Bits
9-8
SIFIFG3 interrupt flag source
00 SIFIFG3 is set with each count, up or down, of SIFCNT1.
01 SIFIFG3 is set if (SIFCNT1 modulo 4) = 0.
10 SIFIFG3 is set if (SIFCNT1 modulo 64) = 0.
11 SIFIFG3 is set when SIFCNT1 rolls over from 0FFh to 00h.
SIFCS
Bit 7 Comparator output/Timer_A input selection
0 The SIFEX(tsm) signal and the comparator output are connected to the
TACCRx inputs.
1 The SIFxOUT outputs are connected to the TACCRx inputs selected
with the SIFS1x and SIFS2x bits.
