24 / 48 page  HT95AXXX Rev. 1.20 24 May 26, 2004 Line Control Function (Supported for HT95A400/40P, HT95A300/30P, HT95A200/20P) Register Label Bits R/W Function LINE (22H) ¾ 6~0 RO Unused bit, read as ²0² LINEC 7 RW 1: Enable the line control function 0: Disable the line control function The line control function is enabled by the flag LINEC Conditions Source to Enable Line Control Function LINEC Operation Mode 1 Normal or Green mode RTC time out interrupt 1 Sleep mode Port A wake-up RTC time out interrupt 1 Idle mode Port A wake-up When the line control source is activated, the PO pin will be set to high signal. Clearing LINEC to 0 will terminate the line control function and drive PO pin outputs low signal. RTC Function Register Label Bits R/W Function RTCC (24H) ¾ 6, 4~0 RO Unused bit, read as ²0² RTCEN 5 RW 1: Enable RTC function 0: Disable RTC function RTCTO 7 RW 1: RTC time-out occurs 0: RTC time-out not occurs The real time clock (RTC) is used to supply a regular internal interrupt. Its time-out period is 1000ms. If the RTC time-out occurs, the interrupt request flag RTCF and the RTCTO flag will be set to 1. The interrupt vector for the RTC is 14H. When the interrupt subroutine is serviced, the interrupt request flag (RTCF) will be cleared to 0, but the flag RTCTO remain in its original value. If the RTCTO flag is not cleared, next RTC time-out interrupt will occur. PFD Generator (Supported for HT95A400/40P, HT95A300/30P, HT95A200/20P) Register Label Bits R/W Function PFDC (2EH) ¾ 3~0 RO Unused bit, read as ²0² PFDEN 4 RW 1: Enable PFD output 0: Disable PFD output, the MUSIC pin output low level. PRES0 PRES1 5 6 RW Bit6, 5=00: Prescaler output= PFD frequency source/1 Bit6, 5=01: Prescaler output= PFD frequency source/2 Bit6, 5=10: Prescaler output= PFD frequency source/4 Bit6, 5=11: Prescaler output= PFD frequency source/8 FPFD 7 RW 1: The PFD frequency source is 3.58MHz/4 0: The PFD frequency source is 32768Hz PFDD (2FH) ¾ 7~0 RW PFD data register L i n e C o n t r o l C i r c u i t R T C I n t e r r u p t P o r t A W a k e - u p F u n c t i o n L I N E C = 1 P O = 1 |
