Field
Description
7
MCZIE
Modulus Counter Underflow Interrupt Enable
0 Interrupt disabled.
1 Interrupt enabled. An interrupt will be generated when the modulus counter underflow interrupt flag (MCZIF)
is set.
6
MODMC
Modulus Mode Enable
0 The modulus counter counts down from the value in the counter register and will stop at 0x0000.
1 Modulus mode is enabled. When the counter reaches 0x0000, the counter is loaded with the latest value
written to the modulus counter register.
Note:
For proper operation, the MCEN bit should be cleared before modifying the MODMC bit in order to reset
the modulus counter to 0xFFFF.
5
RDMCL
Read Modulus Down-Counter Load
0 Reads of the modulus count register (MDCCNT) will return the present value of the count register.
1 Reads of the modulus count register (MDCCNT) will return the contents of the load register.
