71M6533/G/H and 71M6534/H Data Sheet

FDS_6533_6534_004

To facilitate transition to SLEEP mode, which is useful when an unprogrammed IC is mounted on a PCB

with a battery installed, the Teridian production test programs the following six-byte sequence into the

flash location starting at address 0x00000: 0x74 - 0x40 - 0x90 - 0x20 - 0xA9 - 0xF0. This sequence

decodes to the following assembler code:

0000: 7440

0002: 9020A9

0005: F0

MOV A,#40

MOV DPTR,#20A9

MOVX @DPTR,A

; set bit 6 in accumulator

; point to I/O RAM address 0x20A9

; set bit 6 (sleep) in 0x20A9

Transitions from both LCD and SLEEP mode are initiated by wake-up timer timeout conditions or

pushbutton events. When the PB pin is pulled high (pushbutton is pressed), the IE_PB interrupt flag (SFR

0xE8[4]) is set, and when the wake-up timer times out, the IE_WAKE interrupt flag (SFR 0xE8[5]) is set.

In the absence of system power, if the voltage margin for the LDO regulator providing 2.5 V to the internal

circuitry becomes too low to be safe, the part automatically enters SLEEP mode (BAT_OK false). The

battery voltage must stay above 3 V to ensure that BAT_OK remains true. Under this condition, the

71M6533 and 71M6534 stays in SLEEP mode, even if the voltage margin for the LDO improves (BAT_OK

true). Table 50 shows the circuit functions available in each operating mode.
