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?
