17.1.3 ALRMVALH AND ALRMVALL
REGISTER MAPPINGS
The registers described in this section are the targets
or sources for writes or reads to the ALRMVALH and
ALRMVALL in the order they will appear when
accessed through the ALRMCFG<ALRMPTR> pointer.
For more information on ALRMVAL register mapping,
please see Section 17.2.8 “Register Mapping”.
REGISTER 17-14: ALRMMNTH: ALARM MONTH VALUE REGISTER
(1)
(ALRMVALH when ALRMPTR<1:0> = 10)
U-0 U-0 U-0 R/W-x R/W-x R/W-x R/W-x R/W-x
— — — MTHTEN0 MTHONE3 MTHONE2 MTHONE1 MTHONE0
bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 7-5 Unimplemented: Read as ‘0’
bit 4 MTHTEN0: Binary Coded Decimal Value of Month’s Tens Digit bits
Contains a value of 0 or 1.
bit 3-0 MTHONE<3:0>: Binary Coded Decimal Value of Month’s Ones Digit bits
Contains a value from 0 to 9.
Note 1: A write to this register is only allowed when RTCWREN = 1.
REGISTER 17-15: ALRMDAY: ALARM DAY VALUE REGISTER
(1)
(ALRMVALL when ALRMPTR<1:0> = 10)
U-0 U-0 R/W-x R/W-x R/W-x R/W-x R/W-x R/W-x
— — DAYTEN1 DAYTEN0 DAYONE3 DAYONE2 DAYONE1 DAYONE0
bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 7-6 Unimplemented: Read as ‘0’
bit 5-4 DAYTEN<1:0>: Binary Coded Decimal Value of Day’s Tens Digit bits
Contains a value from 0 to 3.
bit 3-0 DAYONE<3:0>: Binary Coded Decimal Value of Day’s Ones Digit bits
Contains a value from 0 to 9.
Note 1: A write to this register is only allowed when RTCWREN = 1.
