4.4 Clock/Reset
4.4.1 Clock
TC6387XB holds the following two Input Clock Pins: HCLK, CLK32
(1) HCLK :
System Clock Input (33MHz Max.).
Basic Clock for System Interface and internal operations.
(2) CLK32 :
Clock Input for 32KHz. The interrupt signal, implied for a SD card insertion and detachment,
shall be generated synchronous to this signal. In addition, this signal is base clock, which input
to a register which set timeout error time on SD data from a SDIO card.
4.4.2 Reset-related items
- #PCLR:
Reset Signal is asserted when power is supplied.
All registers(built into TC6387XB) are cleared by #PCLR.
Be sure to deactivate assertion of #PCLR when power supply and HCLK oscillation (better than 1ms) are fairly
stable.
