The PWMnDBRISE register contains the number of clock cycles to delay the rising edge of the
pwmA signal when generating the pwmA' signal. If the dead-band generator is disabled through the
PWMnDBCTL register, this register is ignored. If the value of this register is larger than the width
of a High pulse on the pwmA signal, the rising-edge delay consumes the entire High time of the
signal, resulting in no High time on the output. Care must be taken to ensure that the pwmA High
time always exceeds the rising-edge delay.
If the Dead-Band Rising-Edge Delay mode is immediate (based on the DBRISEUPD field encoding
in the PWMnCTL register), the 12-bit RISEDELAY value is used immediately. If the update mode
is locally synchronized, this value is used the next time the counter reaches zero. If the update mode
is globally synchronized, this value is used the next time the counter reaches zero after a synchronous
update has been requested through the PWM Master Control (PWMCTL) register (see page 1683).
If this register is rewritten before the actual update occurs, the previous value is never used and is
lost.

compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
