Bit 7: MFSYNC Enable (MFSEN). This configuration bit enables the 2kHz output on the MFSYNC pin. See Section
7.8.2.4.
Bit 6: FSYNC Enable (FSEN). This configuration bit enables the 8kHz output on the FSYNC pin. See Section
7.8.2.4.
Bits 3 to 0: Output Frequency of OC7 (OFREQ7[3:0]). This field specifies the frequency of output clock output
OC7. The frequencies of the T0 APLL and T4 APLL are configured in the
Digital1 and Digital2 frequencies are configured in the
is controlled by the value of the OCR5.AOF7 bit.
AOF7 = 0: (standard decodes)
0101 = T0 APLL frequency divided by 48
AOF7 = 1: (alternate decodes)

0 = Disabled, driven low
1 = Enabled, output is 2kHz
0 = Disabled, driven low
1 = Enabled, output is 8kHz
0000 = Output disabled (i.e., low)
0001 = 2kHz
0010 = 8kHz
0011 = Digital2 (see
0100 = T0 APLL frequency divided by 2
0110 = T0 APLL frequency divided by 16
0111 = T0 APLL frequency divided by 12
1000 = T0 APLL frequency divided by 8
1001 = T0 APLL frequency divided by 6
1010 = T0 APLL frequency divided by 4
1011 = T4 APLL frequency divided by 64
1100 = T4 APLL frequency divided by 48
1101 = T4 APLL frequency divided by 16
1110 = T4 APLL frequency divided by 8
1111 = T4 APLL frequency divided by 4
0000 = Output disabled (i.e., low)
0001 = T4 APLL frequency divided by 5
0010 = T4 APLL frequency divided by 2
0011 = T4 APLL frequency
