I want to use the Vybrid LPTMR @ 4004_0000. It has 4 registers: CSR, PSR, CMR (compare), and PSR (counter). The problem I'm having is lack of documentation. There is nothing in the RM or any of the ARM manuals that I can find regarding the LPTMR. This is what I have found so far:

LPTMR_CSR_TEN         0x01    (count enb??)

LPTMR_CSR_TMS        0x02

LPTMR_CSR_TFC         0x04

LPTMR_CSR_TPP         0x08

LPTMR_CSR_TPS         0x30

LPTMR_CSR_TIE          0x40   (interrupt enb??)

LPTMR_CSR_TCF         0x80

LPTMR_PSR_PCS         0x03

LPTMR_PSR_PBYP      0x04    (prescaler bypass???)

LPTMR_PSR_PRESCALE     0x78

 

Anyone know what these bits do?
