Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
PWM Clock Gating Control
This bit controls the clock gating for the PWM module. If set, the module
receives a clock and functions. Otherwise, the module is unclocked and
disabled. If the module is unclocked, a read or write to the module
generates a bus fault.
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
ADC1 Clock Gating Control
This bit controls the clock gating for ADC module 1. If set, the module
receives a clock and functions. Otherwise, the module is unclocked and
disabled. If the module is unclocked, a read or write to the module
generates a bus fault.
ADC0 Clock Gating Control
This bit controls the clock gating for ADC module 0. If set, the module
receives a clock and functions. Otherwise, the module is unclocked and
disabled. If the module is unclocked, a read or write to the module
generates a bus fault.
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
ADC1 Sample Speed
This field sets the rate at which ADC module 1 samples data. You cannot
set the rate higher than the maximum rate. You can set the sample rate
by setting the MAXADC1SPD bit as follows (all other encodings are
reserved):
Value Description
0x3 1M samples/second
0x2 500K samples/second
0x1 250K samples/second
0x0 125K samples/second
0
ADC0 Sample Speed
This field sets the rate at which ADC module 0 samples data. You cannot
set the rate higher than the maximum rate. You can set the sample rate
by setting the MAXADC0SPD bit as follows (all other encodings are
reserved):
Value Description
0x3 1M samples/second
0x2 500K samples/second
0x1 250K samples/second
0x0 125K samples/second
