4 / 79 page SM470R1B1M-HT SPNS155I – SEPTEMBER 2009 – REVISED JUNE 2015 www.ti.com The B1M device has one 10-bit-resolution, sample-and-hold MibADC. Each of the MibADC channels can be converted individually or can be grouped by software for sequential conversion sequences. There are three separate groupings, two of which can be triggered by an external event. Each sequence can be converted once when triggered or configured for continuous conversion mode. For more detailed functional information on the MibADC, see the TMS470R1x Multi-Buffered Analog-to-Digital Converter (MibADC) Reference Guide (SPNU206). The ZPLL clock module contains a phase-locked loop, a clock-monitor circuit, a clock-enable circuit, and a prescaler (with prescale values of 1 to 8). The function of the ZPLL is to multiply the external frequency reference to a higher frequency for internal use. The ZPLL provides ACLK to the system (SYS) module. The SYS module subsequently provides system clock (SYSCLK), realtime interrupt clock (RTICLK), CPU clock (MCLK), and peripheral interface clock (ICLK) to all other B1M device modules. For more detailed functional information on the ZPLL, see the TMS470R1x Zero-Pin Phase-Locked Loop (ZPLL) Clock Module Reference Guide (SPNU212). NOTE ACLK should not be confused with the MibADC internal clock, ADCLK. ACLK is the continuous system clock from an external resonator/crystal reference. The EBM is a standalone module that supports the multiplexing of the GIO functions and the expansion bus interface. For more information on the EBM, see the TMS470R1x Expansion Bus Module (EBM) Reference Guide (SPNU222). The B1M device also has an external clock prescaler (ECP) module that when enabled, outputs a continuous external clock (ECLK) on a specified GIO pin. The ECLK frequency is a user-programmable ratio of the peripheral interface clock (ICLK) frequency. For more detailed functional information on the ECP, see the TMS470R1x External Clock Prescaler (ECP) Reference Guide (SPNU202). Table 1-1.
